WesBank - Shocking customer service

I have had the worst experience dealing with WesBank after the Covid 19 Lockdown. Wesbank is financing my vehicle and I have never had a problem until now. During the lockdown I asked for payment relief which was granted even though my money was deducted. After lockdown I was asked if I still needed payment relief and I told them it was not required anymore. When I needed it, they took my money and now I am back at work and all is better. They never deducted for October 2020 and when I phoned them, they told me that my payment relief has been approved, I accepted that after arguing with various people. Now I am receiving calls telling me that I am in arrears. How is that possible? When I told WesBank about the Covid Payment Relief and the various people I spoke to, they didn't even answer me properly. WesBank just said they will investigate. Investigate what?? Where are all those recorded calls that I made??? WesBank will NOT finance my next car. Never again.
