Damaged parts, fitted with old parts/ boere mark a plan situation, no respose, poor repaire service

My car had accident 25 February 2018, dial direct did the whole assessment as they said, the car was claimed to be complete nearly two months after the accident. On arrival to fetch my car, the car was not fixed completely they have cheated on the assessment, some parts were later reworked an old parts were affixed, a boere mark a plan kind of a situation on a comprehensive cover! The following parts were not replaced initially. 1. Wiper washer bottle which was damaged at the day of the impact, I poured water all water came out from the washer bottle after collecting the car, bottle was never replaced. 2. Front bonnet was not aligned, major Gap between the two headlights lights 3. A check airbag sign which indicate a dysfunctional airbag on the driver section which was disturbed at time of the accident, it is coming on now and then. 4. Vacuum pipe from the engine fallen out at the time of the accident was not replaced, the car engine is now at risk of damaging airflow meter which might cost me up to 40k to replace.

I send the car for a rework at their selected service providers renewit greenstone and this is what has happened!

1. A new Washer bottle was not replaced, they put an old one or repaired it! it looked old not new! boere mark a plan of a situation to a customer that pays comprehensive insurance on a Mercedes Benz! which now i seat with an old part that is waiting to fail! 2. They claimed to have sorted the airbag but the faulty airbag light is coming again!, i have informed my lawyers about this issue, should i have an accident on that car and the airbag fail to lodge my lawyers will sue dial direct for failing to address this! I have all signed evidence of the tried rework by their service providers with my lawyers 3. The vacuum pipe was claimed to have been ordered by their service provider, 10 days has already passed no Vacuum pipe! 4. Front bonnet still not aligned

I call dial direct repairer service division, they will listen to my complain and never comeback to me, i was left out to deal with their service provider which i was not suppose to do so, since i am not the one who send the car to RenewIt greenstone! I PAY FULL COMPREHENSIVE COVER ON A MERCEDECE BENZ AND ALL CHEATING WAS DONE ON MY CAR i want all fixed, i will take this matter further if they fail to resolve it within two weeks
