Horrible service/harassment

I am receiving calls from Edgards daily to make an arrangement on an account that does not make sense to me. I disputed a balance of 7K and requested them to provide documents or a call recording of me agreeing to the mentioned policies and a statement reflecting the last purchase I made. Suddenly my balance is no longer 7k but 3k, I want to know what happened to the 4k, policies and where is the statement that I requested in order for me to start making payments. I am not getting resolution instead I am being harrased by their rude consultants asking me why am I not paying the account instead of referring to notes stating why.
