I just received a summons from a law firm suing me for a credit card that I didn't open. My mother opened the credit card without my knowledge and now I am being sued for unpaid bills. I never once recevied a bill and the address on what they sent me is not even mine. Do I still have to pay for a credit card that I didn't open? The address is not mine and I've never recevied a bill and they didn't call me or try to contact me until it went into collections. What can I do? Please help.
