Skoda - Fabia — worst service from Gurudev Motors

Address: Tamil Nadu

Dear Sir,
I am having a Skoda-Fabia car and this is my 3rd car from Skoda before I had a octavia and a laura.
I met with an major accident at highway 3 months before.
The car was towed to gurudev motors ,vadapalani,chennai and after 3 days,the attendent from gurudev motors called me and confirmed that the surveyor from insurance company [ ICICI ] have examined and have have to pay an advance of Rs.50000/ to start the work .
I have just escaped narrowly from a major accident and I don't know why they ask the advance amount for the work and I told them i will pay the entire amount at the time of delivery.But they refused.
Now, I have paid Rs.50000/ to them and now they called me today and told that I have to pay another Rs.50000 for the work to get started or I can take back the car and look for some other garage.
If I have to pay some advance for this work, then I can go to the local mechanic , there is no need of a dealer service.
I have never seen such a worst service company like Gurudev motors.
I am thinking of calling the insurance company tomorrow and take the cash back from gurudev motors and tow the vehicle to some other garage.
Jayaprakash.
