Another one that keeps calling but no message - now blocked

Caller: charity prime

l called back and heard a recording saying it was Charity Prime

Caller: Charity prime

Calling on behalf of charities, raising money.

Missed call, no message left.

You block this number and they call from a slightly different number, a few digits later or earlier in the sequence. Annoying because it’s impossible to block every number! IF NO ONE ANSWERED OR CALLED BACK THESE UNSOLICITED CALLS THEY WOULD STOP! Think about it. If you get a phone call and no message is recorded, it is not important! Ignore it

Missed call. no message left I called back charity.

No one on the other end when you answer ... just block the number!
