Discover Credit Card Complaint

Discover Credit card department,

APR or interest rate California

I called DISCOVER card to pay my balance in full with the interest included. I specifically told the representative on the phone that once my bill was with interest was paid in full that I did not want to be contacted in any way, not by mail, email, or phone calls. Discover clearly did not log my request down. I also told them that " I wanted my card account closed and my credit report to state '', " account closed by the consumer and all negative and late payments removed from my credit report. '' Despite all my request to DISCOVER card I am still receiving letters in the mail stating that I own them $150.00. The letter balance has me paying $7500.00 but they stated I only paid $7400.00 in the current balance so they can continue to harass me for money and try to nickel and dime me for more money. I want the harassing letters, email, and phone calls to stop. I also told the Discover card representative to delete my personnel and bank information since my account is closed with them and there is no need to have that anymore. DISCOVER card told me that they would not only be keeping my personnel information but they well be storing it for sometime to do what ever they want to do with my info.
