Don't bank with Capitec Bank

Having banked with Capitec Bank for close on 15 years, and just having opened a business account with them, I'm now about to close all my accounts with the bank. I went into the bank last Thursday to close my personal credit card that I was not using any longer. Spent 45minutes at the bank closing the account and they told me the account was now closed and I would not be getting any further charges on the card and they cut the card up in front of me. Two days later a R6.00 charge appeared on the card (via the banking app) I opened the account to see what the charge was for and saw that it was an admin charge. On phoning the bank today to query this, they have now said that there is a R50.00 additional monthly charge on the account as I re-opened the account via the app. No one said I must not open the credit card on the app but I guess it it just another easy way to get more money from clients. I tried speaking to a supervisor, but she said she could not do anything for me. I'd need to go into the bank again and go through the entire process once more. I'll do this when I go in and close all my accounts
