Get these guys off our phones

Caller: Sam

Calling about my gas and electricity

Didn't leave a message, been getting daily calls from the same bank of mobile numbers

This scumbag called me, breathing heavily down the line like a pervert.
A week later he calls me again saying he's from Energy Savers. I realised I'd spoken to me previously from a different number and at the time I asked him to remove me from his contact list. So I said, remember we spoke last week and I told you my rates are better than what you can offer me? He then hung up like a coward
