Caller: said was from Power Connect

received call on my mobile, male voice, from this number asked who they were, said "Power Connect", don't know of them so hung up straight away, called the number back on work landline, rang for ages, then recorded message from "Julienne" female voice

They rang, I answered, no one spoke, they cut off the call.

They rang in the evening just when it’s time to relax and didn’t leave a message. Added number to my blocked list. Wonderful peace and serenity!!

They rang. I answered. There was a noise a bit like someone said "ag" but otherwise was all quiet and then they hung up.

Caller: Max

Answered and was told it was Max Power. They told me to strap myself in and feel the G’s

I answered the phone then they disconnected. Because of work from home arrangements my work phone has been forwarded to my personal mobile - not sure if answering as a business threw them.

I believe a scam caller, from some compare electricity market company.
