Dent Doctor's service is truly disappointing

I had a small accident where my front bumper was damaged. My car went in to Dent Doctor Honeydew for panel beating with my speedometer working. Apparently during panel beating the Airbag light kept coming on so they fixed the problem BUT broke something else and refuses to accept responsibility for it. when sorting out the airbag light they somehow messed with the speedometer as both electrics sit in the same box. The day the car was fetched from Dent Doctor after panel beating the speedometer was not working. This went under investigation on the 1st of April. i only received feed back from them on the 5th of May from the assessor stating that it is \wear and tear". All other parts of the cluster is working perfectly eg. the rev counter and the petrol gauge etc. It is very clear that during panel beating something went wrong and Dent Doctor refuse to accept responsibility for it and fix it.<br> <br> """
