ACCOUNT STIIL NOT UPDATED AFTER PROOF OF PAYMENT

I have written a review on the 3rd of August and received a reply as well as a telephone call from customer service. I was assured the issue would be resolved and I would no longer be HARASSED by consultants. That however was never the case as I still received text messages and today received a call and the consultant accusing me of not paying my account and she does not need to listen to me. I look at the number of complaints of people with the same problem that clearly shows a pattern of incompetence. How can all these clients be wrong? I have lodged a complaint to the NCR as well as CFDC in this regard. I have sent proof of payment in the form of my bank statement as well as a foto of my cellphone app of the proof of the payment transaction and still the payment has not been allocated to my account and still they want me to provide proof that it was paid to their account.
