What a waste of time

About 2 months ago i queried about green backs on my credit card and the charges and found it wasnt worth it, Just to find this out took about 15mins on hold most of the time. Then to have find out about to get a shop card which no one ever informed me about took another 10mins on the call. Then when they decided to cancel the greenbacks on the credit card they cancelled both my cards without informing me and never sent me a new card. When i went to find out why my cards wernt working they had been cancelled. Firstly they sent me a shop card which wasnt even linked so again call them again and eventually get a new card sent. Then we spent about another 30mins on the phone with a credit card specialist only to tell me i declined to get a new card at the branch and must pay for a new card... Yet they look on the system and it doesnt show why decliined. How can a company so big have such a slow and shocking unprofessional customer care. Seriously thinking about if i will carry on with nedbank even if i have been with them for 20years...
