Called 6 times in the past week. Rushed into getting a quote for British gas and forwarded me to them. Never asked if I wanted to switch provider. Explained to British Gas that this was a cold call and I was happy with my provider which they marked on their record.

I got a call from them saying they're from GoCompare and they want to give me a better rate on my electricity and gas bill for the upcoming cap in July as well. Knew my address and name which was suspicious to me. The woman was very aggressive and rude over the phone so I hung up. They also called me yesterday but I didn't answer only today. I blocked it. I wouldn't answer honestly it is better to look for better rates yourself online than risk over the phone.

Had a potential scam call this morning saying they were from Go Compare. They knew who supplies my Gas & Electricity and said they could guarantee to reduce my bills on the new price cap and the one coming in July. I told him that I wasn't interested as I don't take advice from cold callers. He hung up.

The woman claimed to be from British Gas. I knew something was wrong, when she couldn’t get anything right about me

A call claiming to help people change energy supplier for better rates. I said I wasn't interested and she kept pushing, to the point she became argumentative about why I should change and get a better rate, I said I am happy with my supplier and that I am perfectly capable of shopping around if I wanted to find a new supplier. I already had this page up whilst I was on the phone still so I already had my wits about me but her attitude was a bigger red flag. Anyone in sales knows that if a customer isn't interested you're far better off calling other people than you are arguing with them.

I presume scam as it asked for my PIN number.

Said they were calling from ‘bill compare’. Wanted to find me a better deal on my electricity/gas supply. Explained I’m happy in my current deal. They seemed dismissive ‘don’t you want cheaper’. I explained I’m able to shop around myself ‘but we can do that for you’. Explained I don’t want help, happy to do it myself. Then hung up! Australian/New Zealand woman - they rang twice before I picked up. I don’t know if it’s a scam but I wouldn’t trust any of these calls. Looking at other comments, looks like it could be a scam
