I have recieved about 9 calls from this number and since they can't be bothered to leave a message .. I am not going to bother to pick up ... anyone that has an idea how to block them and show them that they are wrong since I owe nothing to nobody ... I would really appreciate it :)

If I had to guess, I'd say Credit One Bank. I don't know that for a fact, though. The three calls so far this morning fit their pattern. Anyway, they can't be bothered to leave a message, so I can't be bothered to answer their calls. BLOCKED!

Same here. Tried calling the number to get, "this toll free number not dialable from your area." Obvious BS answer service. Probably a scumbag bill collector.
