FNB ...you suck

I had a EXTREMELY HORRIBLE experience with my cheque card for 4weeks with FNB... I have been using this card for purchases a specific way (manual transactions) for 6+years....without any problems EVER,, Then EVERYTHING CHANGED IN A WEE****!! The problems started after my 1st transaction for February on the 13th February... On the 20th when I put another order in, my card couldn't be allowed doing it the manual way, "transaction not allowed" was given on the card machine, as soon as the specific code was added to the payment, and obviously the transaction didn't go through on my international company's side... This order and transaction was tried several times without success. NEVER was there ANY call, email, or SMS to me... or newspaper article about changes on any kind of manual transactions not allowed..!!! Even my FNB branch STAFF DIDNT KNOW the answer and couldn't answer me... I sat every week until the 17th of March 3 days per week in the bank for answers...more than 12 calls were made from the bank...just to get a PATHETIC answer back after 4 weeks.... FNB force you to register for online banking which I didn't want to do, and yet that didnt work either!!!! I might do it at a later stage....not now...OR GO TO ANOTHER BANK.... I am not experiencing the same problem with my Capitec card ....
