Edcon (Jet) worst customer services ever.

I have an account with Jet, I paid R450 on the 2nd May 2020. It has been four months already when I call in to find out how far they are on tracing my payment, I am being told there are many people with the same inquiry. I transferred the payment following the rules Jet sent me, to pay on their FNB account, I used my app to pay. I am being told I should highlight the payment or find the sms I got when I made the payment in May although I provide them with my bank statement. A lady or gentleman by the name of Amukelani asked for my proof of payment, I sent the bank statement, he/she never gave me any response as to how long and far they will fix the issue I am the one who's busy running around calling Jet. They even tell me about their remittance department that is a failure of a department o it's own. I give up. Jet is not lazy in sending me payments that are due though they are lazy in tracing the payment I made four months ago.
