Bad Service

I took my polo playa to VW ( lind saker boksburg) for a service,my car was fine running well,but after it was serviced by lindsay saker boksburg,the speed gage didn't work and i had to drive from Gauteng to Limpopo not knowing how much speed im driving,when i switch my car on theres too noisy on the engine,i manage to get someone to fix my speed gage becouse i might get ticket for speed limit for R600.im sitting with a problem on engine now,im scared when i drive my car coz i might stuck anytime,they phoned me i told them the problem,they promised to get someone to phone me but no one called me since then,you must be carefull with lind saker boksburg,those guys they dont know what they doing there,they ****ed up my car,im sitting with problem now,i paid guys to ruin my car not to service it,i wont refere any customer there,time keeping is bad aswell,they tell you to fetch your car 4 oclock you will only get it 5H30,they dont care about a customer,is the last time i took my car there for service,never ever go there otherwise you will end up sitting with a problems like me,
