Shocking Charges at Discovery Bank

This morning i decided to move my Discovery credit card from FNB to the new Discovery bank, what a big ****en mistake!!! After selecting the option that will give me similar monthly charges for my card, i got shocked by it jumping 100%. I immediately phoned Discovery and queried this, sorry i should have read the T and ****en C'ss better, was there reply... When i wanted to reverse the move i was told it can't happen, and if i close the application then my original card with FNB will also be closed... how the hell does this terrible monopoly still exist?? I will be leaving as soon as get a better deal at another bank, such as capitec with interest as low as 10.25%
