QVC review: Easy pay financing

In the fall qvc closed my account...they state its a balance owed from 2017...I had a qcard thru synchrony bank..all my purchases were put on this card..easy pays as well. The account went into collections. During this period qvc made several attempts to process easy pay payments...qvc states that the easy pays have not been paid and that it's a separate entitie...finance dept stated this to me...there are 2 entities credit card and easy pays are separate... this is not disclosed and is misleading to the consumer... if there are 2 entities it should be disclosed... it is my right to have this debt validated and qvc says they cant... I have provided documentation that the debt is paid. Qvc will not accept this as they state they need proof that the easy pays were paid. Have filed many complaints and qvc does not respond. .
