CMH sold me a damaged vehicle

CMH Waterfall's Lee Stolz sold me a Mercedes. I picked it up on 10 April & from the first weekend of driving I encountered serious faults. The car was barely moving & I returned it. CMH kept the vehicle & fixed only some problems. I received the car 2 months later & since then it's been a struggle to get the vehicle fully repaired. Firstly, Lee only answers the phone every 10th time & barely ever returns my (112) calls. Secondly, I've not been reimbursed for things that I paid for months ago i.e a Roadworthy certificate. Thirdly, I was promised a car with full service history. 6 months later I have not received a stamped service book. The car is still damaged & now CMH are declining to pay for the damage. In the interim I've discovered the vehicle was in a major accident, was badly repaired & I believe the vehicle has done far more mileage than it shows. The fact that CMH traded in a vehicle without checking it properly is not my fault, I didn't want a damaged car. I've had the most frustrating 6 months. I'm now going to take all legal action afforded to me: My Lawyer, NCC, CCR, MIOSA, Media, etc until they pay. I'm so disappointed with CMH. Be warned-do not buy anything from them.
