Terrible service from ERET.

I went to Eastrand engine and turbo to have injectors replaced on my 2019 Ford Ranger as they are self acclaimed specialists. Although they were not the cheapest, I thought I will give them a try. They replaced the injectors at R23000 and when the technician came back from a test drive, he stated that there was a boost leak. I was happy with the job they did on my injectors and took it back for them to attend to boost leak. They told me there is a hole in the ****ler the size of a R5 coin and quoted R3500 to remove and weld it and therefore I will be loosing power. Made more sense to me to fit a new system for R4500. I purchase a complete stainless system and fitted it myself in under an hour. When I inspected the old system, there was no hole. I confronted them about it and Jolene told it is not the original system that was on the vehicle. She basically called me ****. It ended up very nasty and loud inside the reception area and I left as that is how she speaks to her technicians aswell, even infront of clients. I can't understand the mentality of Jolene, I did not go there to ask for money although the cost of a new exhaust and their diagnostics was R6000. All I wanted was for them find this boost leak that they already charged me for. I even spoke to Alan the owner and we also ended up in a swearing competition. Eventually Alan asked me if I would like to take my vehicle back for them to diagnose it again. I declined as I would not like to go near Jolene or anyone else that tries to make me out to be a **** only to cover for their incompetency.
