Discover Credit Card Complaint

Discover Credit card department,

Closing/Cancelling account Michigan

My DISCOVER credit card account was closed by the company on - - without given any reason. I have remained good credit score and never had any late payment since I got the card on -. DISCOVER has promoted its credit card by promising high cash back on purchasing, however they never give any itemized summery on the cash back credit along with every purchase, so it is extremely difficult to keep track of those credits. There were several times when I make purchase using the affiliate link on DISCOVER website but only end up receive - cash back on the statement ( since they do n't provide any record for those purchase and cash back credit, I have no proof to show ). And now that my account was closed, the cash back credit I received earlier was all gone.
