Rang re gutter cleaning spam call

Scammer

I have previously blocked this number but they keep trying to call. No message left. Typical scammer behaviour

I received a call from a woman with an Indian accent. She said her name was Sophie, and she was calling on behalf of a gutter cleaning business. I hung up on her. This is a warning to anyone who receives a call from this woman named Sophie. Please hang up the phone immediately.!! This call is yet another typical scam originating from an illegal call centre operating somewhere in India.!!

This number called without leaving a message - then exactly two hours later butted into my life again, and there was no message that time either. Lowlife scammer behaviour.
