After service

I purchased a car cash from the branch that was advertised with a full service history, but on closer inspection I realized that the car was serviced privately for the last three services with no record of the timing belt having been changed when it was supposed to. I contacted them twice about the issue and they said they would get back to me, and I am still waiting. As it is not easy for me to cross provincial borders, I personally took the car in for the timing belt to be replaced at my own expense for my wife drives with the car and I could not run the risk of her being stranded next to the road due to engine failure, and I have had no contact from them still. I have also contacted them numerously about the papers for the car as I purchased it cash, and each time they assure me that they will post it to the nearest postnet but as soon as I put the phone down, that is where it stays. It has been about 4 weeks and still no joy. At this moment I am unhappy with their communication and customer service.
