Someone else's card given to me instore

I lost my card and I ordered one to be delivered at the mall of Africa. I got a missed call and assumed my card is ready thus leading me to go to the mall to fetch my card. Upon arrival the bank manager confirmed my card is there and fetched THE WRONG card. I obviously didn't see that's not my card but I asked the lady helping me why my card is black and whether the cards have changed and she said yes. I put in the pin and walked out with Mr Dube black card. I realised after trying to buy something that the card is not mine! I mean I have all the information. I returned the card and noone apologized and I was made to wait without help after reporting the matter. I was on lunch and after waiting I had to go back. I came again on today to collect and still no apology. Is this the new standard Bank that treats honest people like this. Standard Bank gives other people's card's to other account holders? Are we safe? Even changing my address has been a challenge. Do you not care about your costumers?
