Caller: Debt Collector Debt Collector that continuously phones several times a day from multiple phone numbers to stay in the legal gray zone. Dont pick up. Just block them on your phone. If you dont recognize a number be cautious. Once they know you are around to answer the phone I assume it only gets worse. I've had 4 calls today already, before 3pm. It is illegal to phone more than once a day. So they switch numbers and try again and again into eternity. GoodLuck!
