Standard bank arrangements not kept to

I have a titanium credit card with Standard Bank they gave me a 3 month Covid 19 break on my payments. They then informed me that the full amount of R13000 is going to be deducted on the 1 st of October I made arrangement with them to pay it off over 2 months but they still deducted the full amount of my account.

I phoned them and the person was very arrogant said I must phone my bank in 3 days and have it rectified. Why did I sit on the phone to make arrangement and then they still just do what they want to. Yes they helped me over the covid period but where am I going to get money or food and petrol and to pay my bond??
