ABSA - RATHER NOT!

I have app**** for a Credit Limit Increase on my Credit Card 01/06/2020 already. I received a call from the Call Center that I need to submit my documents to ***. I have phoned on the 05/06/2020 to esquire as the 48 hours lapsed. I was then advised that there is a Cheque account still opened on my profile that I closed ± 15 years ago. I spoke to Marco in recoveries who said he will send a request to change the status on the account. I phoned again today 17/06/2020 to esquire if my documents was received, and they have advised that they still have not received them AND that the Cheque account still show not closed. Tiffany, very helpful gave me her personal ABSA email, but still for some reason they do not receive my document. I have managed to speak to Marco again in Recoveries, and he was so rude today, stating that he did submit the request 05/06/2020. It is so strange because if I send a mail to Premium Banking, I immediately receive a Case nr. ABSA should rather not offer Limit Increases.
