Discovery Bank - Still discovering my credit card application

On the 7th of January 2022. I app**** for a credit card with the bank. I incorrectly submitted my application before uploading all the supporting documents. I immediately contacted the call center and they told me to email the supporting documents to the credit department, which I did together with my ID number in the subject field so they could link it to my card application. Due to my busy schedule I forgot about the app and assumed they would contact me in due course. Wrong. Weeks passed and I contacted the bank again they advised they would delete my app and I can start the process over in 24hrs. Wrong. I was unable to re-apply as my initial app was still in process. I called a third time and a reference number was created to escalate the deletion. To date, we are now at the 30th of March 2022, over 2.5 months later, I'm still at the same stage I was at the beginning of the process. I'm not impressed this is not the service I've associated with the otherwise stellar Discovery group.
