FNB CREDIT CARD

So disgusting that FNB can not assist me in a simple things which is so disgusting, for the Record I had a credit card with FNB which I decided to pay in full and close the account, I asked them to close the account and send me a Paid up letter for record keeping which they did, fast forward 8 months later both 2 of my vehicles I settled them and decided to buy a new vehicle and WOW to my surprise FNB made a note that my account was handed over, I spoke to a consultant At Wesbank whom I’m financing a vehicle with and was advised I should call and request a Letter of Good Standing how on earth should I get that? Well I called and stayed on the line holding for 37 minutes once I got through I explained what the problem is and they could pick up settled my credit card and request it be closed if as I don’t need it anymore and requested they send me a Letter of Good Standing NOT PAID UP LETTER and to show how *********** your STAFF IS TO DATE I STILL HAVENT RECEIVED WHAT I ASKED FOR. For the Record STD BANK and MFC has granted me Finance and YOU FNB will NEVER EVER SEE ME SET FOOT IN ANY OF YOUR BRANCHES EVER AGAIN AND I WILL CLOSING OFF MY ACCOUNT WITH YOU IF WHATVI REQUESTED IS NOT RESOLVED IN 24hrs. FNB PLEASE SEND ME THAT LETTER OF GOOD STANDING FOR THIS CREDIT CARD THEN MAYBE I MIGHT CONSIDER KEEPING MY ACCOUNT WITH YOU.
