A representative from Trans World Systems, Inc called my house at XXXX and asked for a XXXX XXXX. Caller Id said Toll Free Caller.The telephone number was XXXX. I told him that there is not XXXX XXXX here. I asked him why he was calling my house and he said to get in contact with XXXX XXXX. I asked if he was a debt collector and he refused to answer me. He told me that he ca n't. I hung up and dialed the number on caller ID. That is when I asked the name of the company. I asked him why he was calling my number and where did he get it? He would n't answer my questions. I told him that he can record this, " DO N'T CALL MY HOUSE ANYMORE. '' Then he asked me for the last XXXX of my phone number because he has XXXX numbers on his list ; I think he wanted to record me giving him my number. Obviously, he knew my number because when I asked him if he was a collection agency when I called back and he said he or his company called me looking for XXXX XXXX. Then he asked for my name which I refused to give. First of all, he has no right calling my house about any debt collections because I do n't owe anybody any defaulted debts. And even if I knew the whereabouts of a person, I would not tell them. Collectors answer no questions ; I answer no questions.Let them do their own work.
