refund takes more than 30 days

Let me start by advising that i usually service my chery tiggo 4 pro here (cmh westrand)for the past 2 and a half years and although some things may turn me off i really am not picky and would usually dismiss these minor discomforts for the bigger picture. This time i had trusted them to repair my car as it was giving the faulty gear box warning. i was without my car nearly 2 weeks while they claimed to have been repairing it. constant excuses and delays . I demanded i take one of their mechanics after i had paid them for the repairs since they confirmed the car was "fixed" & ready to be collected and they were happy to oblige me. we just exited the dealership when the light came back on again. needless to say I was utterly disappointed but happy that their own mechanic was in the car with me to witness this failure. i had to leave my car there again, and i was told later/folowing day that they had to order the parts needed, I can come collect my car again and deliver it when the said part was available. my service agent Sizwe Buthelezi then confirmed to me that this will be covered by my warranty which i found strange as i had already paid R1200 excl VAT for this service when the car wasn't even repaired. i told him i expect to be refunded as i paid for nothing initially as the problem was not even resolved then & as he now confirmed the issue is already covered by this warranty. which in actual fact is already paid for by me when purchasing the vehicle. they should not even assume it is a free warranty. I was then promised feedback as to when to expect the money by COB of the 17th September 2025 to date i have not received any update nor an apology for their poor service. I have made numerous calls and plenty follow ups from my end & tried to reach the after sales manager Zane with no success. it seems he doesn't even care about the aftersales service that he manages. i need my money back because it was erroneously charged. the same dealership had been trying to force me to replace my rear lights for a fluctuating price depending on who you speak to. if i could spare any money it would be for that but i had to prioritize my safety on the road by fixing the gearbox issue 1st. please stop these people form *****ing from me and others. i need my money back. Because they know most people cant access them and we don't know their escalation processes at the dealerships they take advantage of us. I told my service agent i will fight for my money i am not rich or well off as others may be i have to fight to make ends meet. i need my money back! i have all correspondence recorded and all the call attempts i made to them for the past month and i will pursue this till i get my refund.
