Very unreliable service

Took my car to these guys for a gearbox problem. After whole two months with the car they said it's now fixed. The day I collected the car it drove for just a few kilometers and started having the same problem. Since then all I have been hearing is stories and eventually no response at all. Very bad service and my tracker records show they were driving the car everyday which might have made the gearbox problem to be even worse now. My advice is stay away from them.
