Screamers Called their from Vodafone.

Caller: Claim to be an electricity company

Originally claimed to offer me cheaper rates on my electricity account as a loyal customer. Then asked which electricity company I used. This raised some flags. Further flags were raised when I was told I would have to take my phone number off the ‘no spam call list’ to proceeed. I hung up on them and they have called back 8 times in the past hour.
