Unfair Business Practice by Isuzu Meyers Beacon Bay, East London

I brought my Isuzu Double Cab vehicle 3000L D-Teq {2015 model} with registration number JPG 452EC on the 12th February 2024 for them to attend to vehicle cutting out when starting and driving . They checked everything and replaced my rail pressure sensor, removed and replaced my suction control valve. I got my vehicle on the 21st February 2024 after having to pay R12 893,19 with invoice number 2051037. On the 9th March 2024, the vehicle returned back to same problem of cutting out when starting and driving. I decided to take it back on the 13th March 2024 as I was assured that, it was fully repaired and their repairs are guaranteed and even their invoice is written as such. Their mechanic tested the vehicle and also noticed the problem. He decided to change again and put new sensor in case the new one they replaced in vehicle might be having factory fault. Even a second new sensor did not fix the problem of cutting which proves that, my original sensor was not faulty and even not the main reason of my vehicle cutting despite that, they charged me for it. Eventually after they tried all what they can do, they removed my injector pump and injectors and sent them to VC for overhauling. They also removed and cleaned my fuel tank and refitted my injector pumps and injectors when they came back. I got my vehicle on the 3rd May 2024 after approximately two months not having my vehicle. I had to pay again an amount of R18 326,40 with invoice number :- 2052821. I reluctantly paid this second amount as I wanted my vehicle but raised it with them that, this was their return job and their repairs are guaranteed according to their invoice. Why charging me for the same problem of my vehicle but having to pay two times. If that is the case, they should have refunded me my initial payment as it was proven that, my vehicle sensor that they replaced was not faulty. They were not interested in my argument and were not even willing to lesson to my concern and to make matters worse even now if my vehicle can have same problem that means even if I can return it to them, they will come out with something else despite having the same problem. Why are their invoices written repairs guaranteed then. After I got my vehicle I called their customer care number:- 08 000 47898 to complaint about this unfair treatment, and I got their reference number :- REF NO:- 65492 and up to date never got any joy or assistance hence decided to post this unfair business practice for all Isuzu Meyers Clients in Beacon Bay, East London to be aware how I was treated whilst I was having confidence on them. As a result, I doubt if I can even refer any customer to them or bring my vehicle to them after having this treatment.
