getting a replacement card - such torture

At Umlazi Mega City branch I was unable to get a replacement card because the letter I had with me had no date. At the Edendale mall branch, I was sent back because I had a letter from my other bank and it had a pin. I removed the pin and offered to write consent for using that letter because I didn't have another letter, but she refused and sent me away. I am now at the scotsville branch. Brought a letter but I couldn't havean African bank proof of residence, luckily I had another. I have been waiting for an hour for the manager who is supposedly the only one who xan issue the cad to me. Over the phone with the lady who was assisting me, she said she will be at the branch in 15min. It haa been 45 and still counting. I feel this is unprofessional, there should be a plan b for if a person responsible for a task is unavailable due to whatever reason. I do not have all day to wait for people who won't even explain themselves, also because he/she knows there is a client waiting, and they haven't been here in the time they stipulated, it is their duty to inform their staff to inform me of further delays. cards should be sent to us when they expire. I am perplexed, this is utter bull.
