Audi Pinetown up to ****

I wish i couldgive u no stars at all or if possible minus stars. We recently bought a Audi A4 from Pinecars in durban Pinetown. Since we got the car we just had problems with oil pressure . We took it to Audi Pinetown not even a month after we got it. Audi charged us over R25000 to change timing chains and who know what else, promised us the car will be fine now. A WEEK AFTER THAT THE SAM PROBLEM..... TOOK IT IN THEY DID NOT RESET THE COMPUTER. We drow the car maybe two months still, the service can due and we took it to the place Pinecars told us to use. About a week after the service the oil pressure light comes on and we phone pinecars they told us to call Audi. Took the car to them and they told us it is due to the aftermarket oilfilter. WE PAID R3164 for a new filter. And still. We got the car back on Wednesday the car was standing as my husband was on standby and drove with the work bakkie. Last week Saturday we took the car out, we did not drive 70km and the FLIPPEN LIGHT CAME ON TWICE AGAIN. Took it in on Saturday but they could not help us. So Monday came took the car in and still to this day AUDI PINETOWN HAS NO FLIPPEN IDEA WHAT IS WRONG WITH MY CAR. Never seen such poor service in my life and if I could I will take this to Cartblanch.
