My kid got a call about a boiler, claiming someone would come over. They never actually asked for any personal info though. Pretty sure it was some sort of scam.

Got a call from a woman claiming to be with Domestic and General. She said she needed info about my boiler because apparently, they didn’t have it in their records. Since my boiler and some other appliances are actually covered by Domestic and General, I’m pretty sure this was a scam!

I got a call where the person asked me to give my full name and address. When I refused because I wasn’t sure who it was, they got really rude. They said they were from Valiant but if that’s true, they were super unprofessional.

They claimed to be from a life insurance firm and asked if I wanted to switch my policy to them for a cheaper rate. Then they asked for my bank info. I reported them to the police because it felt like a scam.

The person on the phone kept pushing hard about me needing life insurance, even after I told her I wasn’t interested at all. She was quite impolite too.

He asked me why I don't have life insurance. I told him I just don't want it. Then he went on about needing it when I have kids, but I still said no. He asked if I was really sure, I said yeah, not for now. After that he said he’d ring me again in a month or something. I told him no thanks, I’m alright without it.

Got a call from 03301007640 (UK) twice back to back on my mobile, within about 10 minutes. I told 'em straight away on the first call that I was out shopping. They said they were nearby and asked if they could come round today to check my Vaillant boiler. This wasn’t how Vaillant usually gets in touch with me, so I found it a bit fishy.

I appreciate the info, it definitely put me at ease. I got four calls all within an hour and every time I picked up, there was just silence. I own a Vaillant boiler which was serviced not long ago, so I’m thinking maybe their phone system is acting up or something.
