They called a mobile number that had since been re-released to a different person. It seems clear, that this Energy Company has lost their desire to keep the customer database up to date. In order for me to halt any future calls from them, I was to call them back with my name. However, the mobile number they have, obviously doesn't match the name. The unloaded some sort of taped shpiel and then they hung up.

Joke's on them. Hahah!

Asked my name, I responded, then hung up, tried calling back but engaged. 5:15pm on a Friday.
