ABSA Credit CARD Circus!!!!

ABSA is a circus!! I use my credit card to pay international suppliers of my business. Today I had to do an urgent payment, only to discover the payment is not going through. I transferred more than enough money to provide for the transaction. Phone the helpline, hold on for almost 30 minutes before a consultant became available, only to be told ABSA upgraded my Silver card to a Gold one, and this one will not work anymore. I will receive my new card in 4 workdays. NO COMMUNICATION was done, and my current card was valid till 2020. Also, I am not able to transfer the money for the payment back into my check account. I only get a message "HOT CARD" . How can ABSA just decide to deactivate your account due to an upgrade that I did not request, or consented to. And now I cant even access my own money that I deposited into the card. Not to mention the stress and delay it is costing me for not making my supplier payment in time!!! I am livid, and is going to close my account first thing next week. Hope all other clients affected by this unprofessional act do the same!!
