[Resolved]  Maruti Udyog (Dealer - Jagrut Motors) — False assurances and huge delay in providing services

My faith in Maruti Udyog and it's services is being put to severe test by their dealers Jagrut Motors, Ratnagiri.
The Maruti 800 DC I had bought 9 yrs back has served me and really well and has become a part of our family.
I had to send my car 4 months back for repairs after meeting with an accident.
For the last 4 months I have been trying to get my car back but everytime some new excuse crops up. Jagrut Motors' staff has shown a very callous attitude and have caused me greater mental trauma than the accident itself.
I was given a call on 29.11.09 to come and collect my car which had been fully repaired. I visited them on 09.12.09 but to no avail. It seems they suddenly detected a problem with the AC!
I was forced to make this complaint today after Mr. Prashant More from Jagrut Motors called me up today to yet again delay the delivery of my car. Apparently, within 4 days of my visit to their workshop the battery also developed some problem!

I stay about 125km from Ratnagiri and it is not easy for me to go and scrutinize their work regularly. For the last 4 months they have been assuring me that I'll be getting my car within the 'next two days'. I have already made 5 visits to their workshop.
How many more visits are required?? Do I need to remind them that they have my car or are they busy looking for spurious parts to replace??
Now I have started doubting even the quality of work that Jagrut Motors will be providing me with considering their false assurances.
I only wish to get my car back with Genuine Parts and a genuine bill (they are charging a huge sum and keep on increasing it) as soon as possible.
It should not take 4 months to repair a car with genuine parts. I hope people at Maruti Udyog take note of the kind of work Jagrut Motors provide as Maruti Dealers. Their attitude brings a bad name to Maruti Udyog also.
