Received call from this number.  Male CSR was rude. Stated did I live at an address in San Antonio TX...I stated I HAD lived in San Antonio but not at that address.  Wanted me to verify last 4 of social.....not going to do that!  I refused to give them any info, but kept insisting I had NEVER lived at the address they stated.  Very argumentative on the phone and kept stating they could tell me nothing unless I verified my social.  I AM NOT giving out my social to anyone over the telephone who is giving me bogus information of where I have lived!!! I always pay my debts so I have no info who this debt collector could be!!  Beware people........DO NOT give out nor verify your social over the phone EVER!!!!!
