My child received a call from a dodgy boiler company claiming they would be stopping by for a visit. They didn’t provide any personal information, which raised my suspicions. Definitely not to be trusted!

I received a call from a woman claiming to be from Domestic and General, asking for details about my boiler because, purportedly, they didn’t have it documented. However, my boiler and other appliances are all registered with them, which raises a massive red flag! I’m convinced this is a scam of some sort!

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 really appreciate the reassurance! I've had four calls from them in just one hour, and each time I picked up, there was complete silence on the other end. Given that I own a Valliant boiler and they’ve recently done some servicing, I suspect there might be a hiccup with their phone system.

I received a call from a woman inquiring about a Mrs. xxxx. I informed her that she had reached the wrong number. However, she proceeded to elaborate on the fact that Mrs. xxxx has a boiler service agreement or something along those lines. I had to interject and firmly tell her, "You've dialled the wrong number!"
