Absa you disappoint big time

I am an Absa vehicle finance cleint. I financed a vehicle in August 2020 from a dealership called Saber Cars in Benoni. Its been 5 months going on 6 months,since my vehicle has been in the workshop 3 times with the same problem. I approached Absa as I approached the dealer to swop out the faulty car they sold me. The credit act covers me against untruthful dealers like this. A lady by the name of Phumza contacted me saying they are investigating and awaiting a response from the dealer. Today I received an email from a lady called Samantha Banks, she only took into consideration the dealers side never asked any questions or conducted a so called investigation. No documents were collected either but a decision was made on behalf of absa by her not to assist. She took the known untruthful dealers word for it. They think I want their funds for repairs, NO I dont . I required this faulty vehicle to be swopped out. Why was no proper investigation conducted , is this the type of employees absa employs ,is this the way absa conducts business and values their clients. Was the dealers word the only word taken into consideration as they are of higher financial status? Does this investigator have any mechanical knowledge or any knowledge on how to conduct a proper investigation. ? Is this how Absa protects their clients against cheating dealers?
