They are a bad service

Some time last year I was driving on CR Swart, I was given a pamphelet about Ram Suspension about services to motor vehicle. I took my car for service they serviced it a week later it dripping oil, I took it bad and they realised they did not tighten the oil filter.(really???). then they fixed it. A month ago i took it for gearbox repairs and suspension they fixed everything but when i was driving the car it had a knock on the suspension i took it back and they told it is missing some bolt, not sure why they could not pick it up at first. now im driving the with the knock they promised they will get it within a week up to today nothing. I must travel to Limpopo for easter holidays i dont know if something happens with the knock what will they do? I have been trying to call Peter, he has not been answering my calls nor return the calls. I think they have a very bad service I dont encourage people to take thier cars there for service.<br>
