A woman calling from 'Maury Cobb Attorney At Law ' at XXXX would not disclose the nature of the matter without me giving my date of birth. I did not offer any info. However, she did state my address and last XXXX digits of my social security number to try and get me to offer my date of birth. How she had that information is difficult to understand and of great concern. I told this woman that I have not received any notification by mail on any legal or debt matters. They may be trying to collect a student debt of a relative which was legally dismissed in bankruptcy. I was listed on that loan as a reference. That is my only theory on this. Nonetheless, I am not liable nor is my relative. An investigation is required.
