A man named XXXX keeps calling me from XXXX XXXX XXXX XXXX XXXX in XXXX New York. They use several phone numbers and change them frequently, but the most current XXXX is XXXX. They started contacting me last year about an HSBC credit card debt that was discharged in bankruptcy in XXXX 2011. However, they are VERY rude, XXXX threatens me with legal action, tries to intimidate me, and has even verbally attacked me on the phone. I even had to change my phone number and they STILL keep calling.
