ABSA Credit card Paid up Letter

I have paid up my credit card a year ago. ABSA claimed that they have sent the paid up letter but I have not received it. Upon request they came with 100 excuses and I have delivered all the proof of ID needed and more. Upon the last request, that they did not have my correct email address because I logged the request from my work email, I again supp**** all the info from my personal email that they have on record, still no Paid up letter. How hard can it be to just resend a letter? I am not asking for a kidney!! One thing ABSA does well, is ass the ******, not one person takes ownership of an enquiry.
