Poor customer service - Nedbank

Im a very disappointed and dissatisfied Nedbank client. I have a cheque account with them which comes with rewards shop card. I received my shop card a week ago and was told at the branch that it was activated and ready for use. When i tried using the card it gave a code 06. I went back to the branch to sort the matter out. I was told to use the in-branch phones to contact the card division. I spoke to a Nosipho who requested to speak to a consultant and it was decided that the card needed a recode. A recode was done and was told the card was all sorted and ready for use. I tried to use the card again and got the same code 06. I returned to the branch and was told to contact card division for a new card. Spoke to anothet consultant who told me that a case was logged to the back office to investigate and sort out the matter within 24- 48 hours. The consultant assured me that she will personally give me a call the next day to give an update however this was, evidently, an empty promise. Its been 3 days since i visited the branch and i have not heard from Nedbank and my shop card is still in active. I am on the verge of switching to a different bank as their service has proven to be disgusting to say the least. They come across as clueless and are not proffessional enough to keep to word. Their service is very sub-standard compared to other banks that i have dealt with before. I would be reluctant to recommend to any other person. *** (cell)
