Hopeless, inept,, slow pathetic service

I went to the Cresta branch to change the ATM withdrawal limits on my SAA Voyager cards. Arrived at 11h39 and was only assisted after 12h00 After waiting for close to 30 minutes for assistance, I gave the consultant both my cards - Amex and Mastecard - and requested the limit to be increased from the R1000 it was. She said It could be increased to R9999 and I indicated that she could increase it to that amount. She then found that it could not be increased to that amount and said the limit could be increased to R5000. Again I agreed to the limit being increased to R5000. She confirmed it was done and I requested written proof which she gave me. After leaving the bank and going to draw I found that IT WAS NOT DONE and had to go BACK TO THE BRANCH. The consultant was on lunch and I was told to wait for another consultant. When asked for the manager I was told he is not in and should speak to another lady. When I spoke to this lady she checked my cards and said it had NOT BEEN DONE on the 2 cards even though they are linked and it is one account.
