Insurance claim, 42 days later, no vehicle and still no response from Miway

On the 6th of December I had an accident with my vehicle, the damage was to the bumper and the left back brake light. A1 assist (a towing company that has a contract with miway) towed my vehicle to a miway assessment center. After a week passed I decided to fetch my car and fix it myself. Upon arriving at the assessment center to get my car I was told that the vehicle was not drive-able whatsoever, the person who towed my car wrote on the windscreen that there was no oil in the vehicle. After I asked how this was possible the person at the assessment center told me when they got the car the oil filter had sustained extreme damage, the samp and gearbox underneath the car was also damaged. I contacted Miway with this information and they assured me they would do a reassessment and will find out from the towing company how this happened and then sort it out. It is now the 16th of December and absolutely nothing has been done. When I contact miway for feedback I receive the same response every time, they will have someone contact me with feedback. This is the absolute worst service. I am appalled at how Miway deal with claims.
