Keep a whistle by your phone. When you receive a call and answer, be sure there is someone at the other end. There is a sound booster on their headset and when you blow the whistle, their ear will ring for the rest of the day. It worked for me and the harassing calls stopped.
I RECIEVE FEW CALL FROM THIS NUMBER THAT I BEEN APPROVED....
IVEN YOU HANG UP THEY WILL CALL MINUTES LETR.
HOW CAN I STOP THIS ANNOYING COMOPANY FROM CALLING ME.
I have received 10 calls from these people today. Hit zero and got an operator. Asked to be removed from their list. Got another call and went to an operator again. That operator told me he's "sick of you damn people complaining about getting all these calls". I hung up, and I immediately got 3 or 4 calls from them in a row, so that operator must have "redialed" me somehow just to annoy me.
