Offered an energy provider comparison. I said I’m not an account holder for an energy bill, and asked for my name and number to be removed from their database.
Scam.
I Answered the phone, it was someone speaking to me slowly about an "electricity bill" and asked if I received it which I ended the call as electricity is included in my rent so I don't deal with electricity bills at all. He was speaking to me as if I had one.
