im geting repeted cals from this number dont know who is that

Got a call to inform me that I had deserved a trip for paying my credit card on time. Began to ask me info on my credit call, which I didn't give. Very bad quality of reception. Appeared very suspicious.

This number comes up on my caller id every day I don't know who it is

called twice in 3 mins.would only mumbly on the phone,so i hung up

This number calls everyday at 9 and I answered and told the heavily accented guy on the other end that I was not interested and to not call me because I was on the do not call list. He told me to shut up! I thought I heard him incorrectly but he repeated, "You heard me shut up" I had to hang up before I flipped.
