Called to advise that my next electricity bill will be cheaper as the energy provider has reduced the rate.
Wanted to know info from my last energy bill. Told them the call was not legitimate and hung up.

I had the same thing happen to me, multiple times from this number!

Told me they could give me a cheaper electricity rate and that from next month my bill would be cheaper. It was of course a scam as he wanted to know my details… like address etc…
