Nexa — Poor quality repair work & bad communication from service centre

I had given my s cross zeta, registration number being rj 14 lc 8195, for accidental repair works at prem motors service centre, sudarshanpura jaipur on 13th april 2022.
I was taken a back by the quality of communication that the service centre gave me. There was literally no communication of any sort from the centre. I hav enclosed the whatsapp chat history of the so called group that they have created to update me about the procedure but it was of no use. I was the one constantly asking about the updates. I was not even given an estimate of the repairs beforehand and in the end i was asked to pay inr 2544 saying that insurance has only approved inr 36000 and remaining amount has to be paid by me. The invoice has been enclosed here which includes useless things like floor mats, cockpit spray, interior cover, etc.
The quality of repair is so poor that my new door paint is completely off. It feels too second hand looks like that it has been repaired by a local garage. Even the fender locks are not placed properly. On top of it the alignment of my car tyre are off after i have received it on 30th april 2022. There are a lot of scratches done on the drivers door, photo enclosed. The car seats are so dirty that there is dust all over, photo enclosed. My steering wheels controls are have beome non functional after receiving the car from the service centre. I am not able to understand what these guys did to my car.
On top of all this, there is a very interesting communication that happened on the whatsapp group. On 29th april 2022, at 1643 hours, i had received a msg on the group saying that my car is ready and i should come and receive the car. I asked them to make a delivery of the car and i had to go plan an outstation trip the next day morning on my car. I was waitng eagerly for my car to be delivered. But to my dismay, after more than a couple of hours at around 1925 hours, i again received a msg on the same group that the car will be delivered tomorrow because they have still not received the do.
I have a simple question to make that when they did not had the do then why the hell did they ask me to come and collect the car, when on the job card it is clearly mentioned that delivery will be done basis do only.
I was completely shocked by the lack of professionalism from the service centre. I do not think prem motors, sudarshanpura, jaipur fits into the quality standards of nexa.
I want the repair works to be taken up professionally and my alignment and door scratches to be repaired at the earliest. And i want a spare car for myself as it has already been 17 days without the car and my work and business trips are affected because of this.
