WESBANK destroying my good credit name.

In March 2020 I app**** , and was granted COVID Relief ( I had lost over (95% of income ) . April came and no payment was taken off my account , Then. 1st May Wesbank took payment off for the cars . I sent over 8 Emails panicking about the funds taken out of my account ( These funds were there to get me through the lockdown ) EVENTUALLY they returned the payment . Then in June I app**** for an extension on my COVID Relief ( Still not enough income to cover my expenses ) Again I was granted relief till 1st September . However I noticed on my monthly invoices it said I was in arrears , I queried this and got no response , again in July I got another invoice showing my account in arrears , AGAIN I queried this , no response . Now its August , I eventually got hold of them and THEY tell me that they returned my money in May but I still owe them the money, which is a lie , I was still under the COVID Relief, according to THEM I only app**** for one month ( Why the hell would I, or ANYONE of done that ? ) . This is unacceptable . I do not have the funds to pay both my instalment AND money they claim is in arrears . I will NOT go into a "Payment plan " this is not my mistake its THERES ! I have been with Wesbank for well over 20 years and have never ONCE been in arrears , This is how they treats their customers . Its wrong , my good credit rating is about to be destroyed because they refuse to help or accept they made a mistake .
