I received call from standard bank credit card sales division approved for credit card never received card as yet

Good day i firstly like to mention i am not putting bad picture on standard bank. I received telephone call on my mobile on 13 August 2019 at 11:43am the number was +*** from standard bank call sales center new credit card division. I spoke to nice gentleman name kevin. He informed me that i qualified for standard bank gold credit card for certain limit. The sales agent spoke to my son getting further details whilst on loud speaker. I was advised i would receive the credit card 7 to 15 working days.the agent asked permission if standard bank can retrieve my bank statement on my behalf i did give permission. I did go to the branch that i selected to pick up the card up. I never received any sms to pick up the card i just went to verify on 21 August, the branch has no records of the credit card I even card division from the branch the card division has no records . I thought i would receive the card before i depart for holiday 23 August 2019. Please standard bank, kindly inform me if this was a genuine call from your call center sales offering credit card. if it genuine please inform when will i receive the card. Please note my son will also speak to you give you furth details. I await your feedback urgently.
