Extremely poor and unacceptable customer service

I app**** for the iStore credit card on 18 May 2018. So on Monday Standard Bank phoned me on my correct cell phone number to confirm that they received me application it will be in progress now. On Tuesday it was approved. So Standard Bank sends everything to CDC Couriers so they can deliver the card to me. Standard Bank gave CDC Couriers the incorrect cell phone numbers which means they mixed someone else's personal information with mine and it is highly unacceptable. I have spoken to 6 different people incl CDC Couriers and Standard Bank and no one can help me. I have asked for the supervisor for Standard Bank and the person does not answer. In fact the first person I spoke to by CDC Couriers hang the phone up which is very rude. No one can help and i am EXTREMELY frustrated by Standard Bank service and CDC Couriers service. I am waiting long enough for my card to be delivered. I asked CDC Couriers which Standard Bank branch they working with and they could not answer that so I had to google the iStore Standard Bank number hoping that I phoned the correct branch.
