We've had quite a few letters arrive at our head office, which isn't even the place where deliveries go. They all came on different dates, spaced about a week apart, with various account numbers and each showing a different amount due. We're a tiny charity and have never dealt with this company before. When I looked up the number, it was slightly off - just two numbers different from the real Smartest Energy contact info. This has got to be a scam, so watch out! Don't pay a penny.

So I just got this letter saying I owe £4175 on a business account that I've never even had! It was sent to my home, had my name right but the house number was completely wrong. They wanted me to set up a direct debit either online or by ringing 01903703421. Honestly, no way am I falling for that, sounds like a total scam to me.

Got a letter at my place for my late mother-in-law, who’s been gone for over five years now... The letter demanded payment of a gas bill for £1,623! Thing is, she never had gas at her last flat and as far as we know, she never had an account with that provider. I called them up to explain the situation, but all I got were dodgy and unclear answers. When I checked the real Smartest Energy website, the contact details and address on the letter were totally different from the official ones. Honestly, this looks like a well-planned scam - would definitely watch out for it.

This site is quite clever... but yeah, I think it’s just a scam call.

Received a letter pretending to be from some company, but it had no account number or any real info. When I rang the provided number, I got put through to a lady from Africa who struggled with English. They said something about taking legal steps, but I’m just going to ignore it.

Received a letter at our business address claiming we owe some money and asking for payment via bank transfer with the details included. The sender isn’t someone we deal with as a supplier. I tried ringing the number given but ended up waiting on hold for half an hour and then gave up. The letter warns about possible further steps, but I’m just going to ignore it for now.

Got a message saying a direct debit didn't go through, came from something called 'smartest'. Bit daft since I've never dealt with them. Just blocked the number and reported it straight away.

Got an email with an invoice attached telling me to ring this number. The company named itself Smartest Energy Business, which sounds almost like a legit firm, but the phone number was just a bit off. Honestly, this is the slickest scam I’ve come across yet. Watch out, folks!
