Caller: Telemarketer for gas and electricity offers

2 calls today
1st one I could hear call centre back ground noise and hung up after 10 seconds of no response from caller.
2nd call the caller hung up as I answered.
Blocked.

I called back number (03) 8202 5024 spoke to a guy who said company name is Let Us Compare.

People from this number and others keep ringing to give me a better deal on household costs. I tell them every time that I’m not a homeowner and I live with my parents and they say they’ll take me off the list. Obviously they don’t because they keep calling
