ABSA POOR SERVICE

I was supposed to fly to Fiji, and 6 days before I was to leave, everything went to lock down. I had a week before to call ABSA CREDIT CARD DEPT. and i informed them on my travels. But since I could not leave, my credit card and my banking app. became frozen.I Am now trying to get hold of credit card dept, and to my horror, i get informed that they are closed. How is this possible. I am now stuck here unable to get any use of my card. This is absolutely unacceptable. You then have the nerve to send me e mails complaining it is in arrears. How dare you. Until my credit card is sorted you won't get a cent from me. I can tell you, that when this is all over, i will be closing all my accounts with you .
