Repeated calls daily to my wife's phone. Driving us nuts. Last digit changes for repeated calls. Same caller.

Caller: Power & Gas Spam call

I just hung up and blocked However they just change their number.

Keep calling, don’t take No for an answer.

Caller: Switch Savers (she said)

Say they want to help you find a better deal. Not forthcoming with information, not taking No for an answer, and calling back several times a week from a different number. Very unlikely to be legit.

Won’t say who they are, call “about your electricity bill”, and will call again tomorrow from a different number.
