Ripped me off!

Just had a centre bearing fitted and only lasted a month. I have now had the bakkie replaced from front to back with new propshafts and new centre bearing and its been working fine now for a long time. Sajco Randburg ripped me off for R1500-00. Full propshaft and center bearing plus balancing came to R2200-00 Iv asked for refund and they said they will send it in to be tested. Its about three months and i'm still waiting. Pathetic service! I was also told that the chassis was bent on my bakkie and they could not do balancing. I sent the bakkie for testing and it turns out that there is nothing wrong with the chassis.
