This is the outbound caller for simply energy. They called me and gave a pretty good deal. I then called simply energy direct to confirm that it wasn't a scam. Alas it is their outbound calling centre, and they are from simply energy cold calling with an automated dialer. Even so, I didn't like the practise so I asked for my number to be removed.

simply energy

I have had the same issue!
no answer keeps calling, anybody knows what this number is?

Answered call, no response from caller. So Hung up. No idea who it was, but my guess is its another nuisance/scammer of some sort.
