Skoda India — Spare parts availability for accident repairs

Had dropped my Kodiac Scout (TN88F5599) at SGA Cars Coimbatore on 14th October 2020 for accident repairs in the rear side. I was informed that all the works had been performed by 15 days except for some parts in rear spoiler which had to be procured from the factory. Till now I am getting repeated response that the parts are not yet been billed in the factory and can deliver the car 1 Week after receiving the parts.

I dont understand the reason for the onordinate delay. Having clocked only 5000 Kms I'm desperate to get the work done but the feedback from Skoda makes very dissapointed. Kindly do the needful
