Vehicle does not run after repairwork

My car was taken to Technostar on the 17th September after a collision and I only received the vehicle back on the 16th November. The advisor Francine was very helpful when you can reach her (this takes many calls) but the rest of her team was a disaster. I was told the vehicle was ready for collection. When I get there, one rim is painted a much brighter silver than the other rims. I was told this would be rectified with their service provider. The car starts. The car was not cleaned, with overspray noted on the inside panels. Scuff marks were noted and I was told these would be polished out. I personally called AK (the workshop manager) and asked the car be inspected before delivery as I am signing the clearance without inspecting the vehicle. The vehicle is then delivered to me. Immediately, I reported back that vehicle doesn't start, vehicle is not cleaned properly and scuff marks still visible. body panels do not line up correctly. The rim was not rectified as it was a brand new rim and not repaired. I was told it was repaired and it would go back to the rim repair centre (whereas the insurer only authorized a repair, not replacement). This turned out to be a blatant lie. The rim was repaired and I called AK and his reply was he only inspected the rim, not the vehicle.

Technostar has washed their hands of my vehicle as I signed the clearance (although it was noted as unseen), getting them on the phone takes numerous calls every two hours. I have now reverted to my insurer who will need the car to be reassessed. In the meantime, I am left with without a vehicle. I have 3 other vehicles insured and will never allow any of my vehicles to go back to Technostar. Their work is not the best, the service is pathetic and they will lie to get the vehicle off their site.
