Bad Customer Resolution with credit card Department

have a case where by I was offered a credit cad from African Bank. Before I received my card I got a call from Sibosiso Mdlalose at African Bank He claimed and asked me to go and collect my card from African Bank. I then later received a call from the same Sibosiso claiming to be calling from confirmation department to activate my monthly debit ode on a credit card. To my surprise He had the card no and some part of the back card no and the amount offered all the info was genue until He offered me a barring code to dial on my phone. I then suspected ***** and called the bank for assistance. I was advised that the card will be put on hold status and I can activate again by either an app or going to the branch. The consultant did everything to help at the bank 100%. But the card remained on lost status and couldn't issue a card. He was promise tobe called back until I called the call center again n He was advised to log a call. I was then give a turn a round time of 48hrs my question is why do I have to wait so long after I was told it can resolved immediately and this is not the 1st time I'm experiencing bad service from African Bank.
