Unauthorized credit application from Nedbank

I click on a link online to open a credit card from Nedbank on 25 Feb 2025, A Consultant phoned me to open the credit card and i was advised that that i was pre-approved pending documents. Same day I sent 3 pay slips, bank statement as requested, 2 days went by and no response , then i got an email to send December payslip which was already sent , another 2 days went by i was told the bank statement doesn't show January salary even though 3 valid payslips were submitted. I requested a statement from by Bank which they advised i should print an interim statement to show January January as 3 months statements are automated and cannot be amended , another 2 or 3 days went by and i got another email that they will not accept the interim statement as it doesn't have a bank stamp. I then decided to respond to cancel the application as it was taking way to long ( i have never experienced such an exhausting dragging time to open a card that was done within a day with Absa bank and card delivered 72 hours after. No response on my cancellation email sent on 11 March @ 11am, i sent a follow-up email on the 13th of March and Kerwin assured me that he will cancel it and it will not show on my credit profile as they only did a soft enquiry. 16 March I got a message that my card was ready for collect despite the assurance that it was cancelled and or the fact that they still approved it without the endless documents they were requesting. Can Nedbank give me feedback on this and please ensured that this is closed and my credit profile updated as soon as possible as i have not approved this. Kerwin gave me call again on Monday and said he will be escalating the query as he did cancel, 72 hors later i still have not received anything from him. Please do not call me , just do your wok and fix this mess. How do other banks approve it so early , in a matter of 2 days and Nedbank took 16 days to approve
