Somebody called saying they were from Tesco's fraud team, real stubborn bloke, kept telling me he was just trying to sort things out for me. I got fed up and ended the call, then rang the number on the back of my card. Turns out my card had already been used at a Louis Vuitton in Amsterdam by then!

My phone flagged this as spam right away. When the person asked for my date of birth, I just hung up. I’d suggest using the number on your bank card to call them directly instead. That’s exactly what I did, and I ended up cancelling my card. It’s always safer to be cautious than risk it.

This number really was Tesco’s. I didn’t pick up at first, then got texts threatening to block my card, so I called the number on the back of it. Turned out they were legit and connected me to their fraud team. They said they’d stopped suspicious charges from places like Uber and Costa. They’ve since cancelled my card and are sending a new one. Plus, they gave me a special password to confirm if anything dodgy pops up again. Definitely make sure to call the number on your card if you’re unsure!

Got a call from what seemed to be the Tesco Credit Card fraud team. They said they spotted some dodgy activity on my card and needed me to confirm some details. If you don’t get back to them, I reckon they’ll freeze your account till you sort it out with them.

So this morning I got a call that showed up as spam, so I ignored it. Later, I rang Tesco using the number on my card just to check. Turns out it was actually Tesco. They told me there were two dodgy transactions they refused and had already frozen the online use of my card. Properly sorted, so relieved they caught it!

I got a call from this number claiming to be Tesco Bank’s Fraud dept. I wasn’t sure if it was real so I checked the Tesco app and rang their official number listed there. After speaking with them, they connected me to their fraud team and confirmed the number was legit. So yeah, if you’re doubtful just verify through their app first.

I rang a Tesco number I knew to make sure, and turns out this is a legit Tesco fraud protection line. I was trying to do a third big online purchase in under an hour for stuff to fix up the house, and the payment got blocked. Fair play to Tesco for flagging what seemed like odd activity. If you're unsure, always double-check by calling a number you trust, like the one on the back of your credit card.

I have serious doubts that the individual who called me was anything more than a scheming fraudster, potentially using a genuine Tesco contact number. These con artists seem to believe they have the upper hand, but they quickly lose interest when you don’t engage. My advice? Don’t respond, and wait to see if anything lands in your mailbox on proper Tesco stationery. Spoiler alert: it won’t!

On the 13th of November, 2021, I received three calls from the number 03453666642. Fortuitously, we were out on all occasions, and they left a voicemail on our landline claiming to be from the "Fraud Department of Tesco." I can assure you, it was a scam! Please, whatever you do, don’t press any of the numbers they request-just hang up and save yourself the trouble.

Got a text claiming Tesco was warning me about fraud with another number to come. Didn’t feel right so I called Tesco straight away and they said yep, they had stopped a dodgy transaction on my card and sent me a replacement. It’s legit, but if you’re unsure, just ring the number on the back of your card yourself. They’ll run you through the standard security checks - a bit annoying but much safer in the end!

I’m certain this number belongs to Tesco Bank’s fraud team. I got a text from them today about some odd charges on my card. Later, this number rang me up asking for the 3 digits on the back of my card, but I didn’t share that info. They advised me to call the number on the back of my card, which I did, and they confirmed the call was genuinely from Tesco Fraud. 4th March 2020

I recently got a couple of messages supposedly from Tesco about a payment that was denied at a shop I've never even visited. Shortly after, I received a call from the number 0345 366 6642. When I picked up, I heard a pre-recorded female voice with an American twang. I hung up straightaway, as I typically do with these dodgy calls. If Tesco's fraud team genuinely needs to get in touch, I expect to speak to an actual person, as that’s how it’s been in my past experiences.

Tesco Fraud Dept. provided top notch help and spotted several tries to scam my credit card. I was quite careful and completed their security questions to confirm my identity, then also asked them stuff like where my wife shopped for groceries today. They didn’t mind the security checks at all. Really good service. Properly impressed!

WATCH OUT! Even though this looks like a real number (it's the Tesco Bank fraud line), scammers can copy it and make calls pretending to be from that number. I got a call from it yesterday evening. NEVER share your info, always ring back on a separate official number to confirm if it was really them. This isn’t just Tesco; the same thing happened with Natwest for me. When I checked with them, they said they hadn’t called, but their real number appeared on my screen. Maybe that explains why people are confused in the reviews about whether the number is legit or not.
