I have received phone calls from IC System repeatedly at all hours of the early morning and late evening ( including XXXX on the weekend ). the numbers were originally from the XXXX area code. I was never able to answer the phone, and nobody ever left a message.also called from an XXXX ( CT ) number. In the past 2 days they have robocalled me from XXXX ( ID ) and XXXX ( WY ) and have either not left a message, or I have answered with the delayed response from them and hung up ( indicating a robocall ). I returned their call both times and asked who they were and they refused to give me any information until I verified my address or my social security number. I do not give out personal information on the phone. I suggested that if they wanted to collect from me XXXX which they never actually confirmed who the creditor was XXXX, they needed to send me something in writing, and we returned to other person demanding that in order to do this, i had to give them my identifying information. They hung up on me in the middle of my own sentence about why they would n't be getting my information over the phone. they called me back about an hour later and it was another delayed call without a person on the other end. If i legitimately owe a debt, I am MORE Than willing to pay it, but I 'm not giving out any information over the phone ... not when they clearly already have that information if they are asking me to " verify '' it with them.
