Block the number, easy as that.

Just got a call from this number. I did a survey and entered a competition. Stupid thing to do, I get hounded constantly from all sorts of people.

Just got a missed call from this number, no voicemail left. I always check numbers I don't know on here first rather than just returning calls, so I'm glad I did.

The number is a telemarketer. Won't stop calling me. I wonder which company I am signed up for sold my number!

I am regularly getting calls from this number, and have been for the last couple of weeks. I haven't been answering as I don't know who it is, and a voicemail is never left. Very odd.

This caller is an scam artist. They pretend to be from a charity and they also pretend to be from a company conducting a survey.

Both are not true
