I received a call from a " company '' claiming to collect a debt. Asked me to verify the last XXXX of my ssn. I did n't verify as I suspected it was a scam and the caller got very upset when I requested to have the information sent to me in writing. I asked the caller to state the company name several times and she did not and after I explained to her I 'm not confirming anything because " this could be a scam '', she hung up on me. Basically confirmed my suspicions.
