I called back number (07) 3107 1651 reached voice mail but did not say for what company.

I called back and the phone hung up straight away. I called as a private caller using my landline and mobile then called again using my mobile and the same thing happened with all three. Dodgy!

Automated Electrical Telemarketer

I experienced the same thing just now.

They are an apparent energy broker working with Alinta Energy (unconfirmed) trying to con you into switching but I'm not sure how legit they are. I queried the guy when he was asking for my NMI number for my electricity meter and he promptly hung up on me. Calling them back goes straight to message bank. NOT TO BE TRUSTED!

SPAM! They called and hung up once I answered. Called again about an hour later trying to ask me about my energy bill. I am over here on holidays on a prepaid sim, I dont pay for electricity here LOL
