This was the same GMC credit number as they change the number to trick you in answering your phone

Glass Mountain Capital, collection agency.Calls even when its not you they are looking for.  Solution: Get callers name, company and address and phone, Their supervisors name and person they are trying to contact.with their name and address..  Then tell them you are writing them and FCC and your state attorney generals office and if calls persist will sue.

Glass Mountain Capital has called me numerous times harrassing me about a Citibank account that I have never had. I even checked my credit report to follow up in case someone had used my ss# to open an account and contacted Citibank. They had no record of my ss in their system at all.
