Nedbank cullinan worst service ever

After sittng for about an hour and no one insite to assist. A banker came out to ask me what they can help with only t tell me that i was in the wrong queue to renew my card. Shen advised me to go to enquiries where the queue was extremely long. After another 30min in the queue with no movement i aventually left without a new card. I dont understand why a bank that makes millions of our credit cards can't get a host at the bank to direct you and make sure the branch helps the public in an efficiant manner
