Terrible service

Terrible service, I was paying R218 a month. I phoned on 25 August 2025 to cancel the contract, due to the fact the vehicle has been sold, I was advised that there is a 20 days notice period for cancellation the cancellation date will be 20 September 2025 and the cancellation fee I need to pay is R2650,00 of which I made an arrangement to pay it off via EFT on 08 September. And then to my surprise this morning they went an debit my account R935,00 without notification, and what is this amount for, because they have not yet cancel the contract. I phoned this morning spoke to Boitumelo and had to hold for 20 minutes for supervisor to take my call. Spoke to supervisor Laurenzo who agreed that this was not suppose to happen because they have not yet cancelled the contract, they just decided to put a Naedo tracking for the payment that is not yet due. I want this Naedo to be cancelled. Stop messing up with my credit profile.
