Transaction issue Ohio

I canceled my Discover Credit Card in -/-/- of this year, due to numerous unauthorized charges ( mostly by - 's ) and - disputes that were found " in favor of the vendor '' in excess of hundreds of dollars, although documentation was not properly collected nor investigated properly. I have now received a statement from Discover with a charge dates - ( 2 months after I canceled my card ) for a - warranty in which during a call on -/-/-, Discover informs me " we have documentation that supports the vendors ( - ) charge. '' I however, have been directly communicating with the - Offices of -, and they have assured me that my warranty in the amount of $85.00 was not charged. When I called to complain about this fraudulent charge to Discover, they REFUSED to give me anyone 's name, and would only give me a " p.o.box address to lodge a complaint. '' They also threatened ( bullied - me that " if you do n't pay, you will be charged late fees. '' As an independent -, I have spent a PLETHORA of hours upon hours from -/-/2016 to Present, fighting with Discover, which has equaled additional financial loss. Please tell me how a credit company in which I separated services with over 2 months ago is holding me in financially responsible and - for unauthorized and fraudulent charges to a credit card THAT NO LONGER E-ISTS?
