Sai Service Station — Not happy with service

I get the feeling that Sai service is all about show me the money. Had gone to sai service lower Parel since my car was water damage and was told to keep the water in the car for 2 to 3 weeks before insurance company sends in their representative to check the car. I did have a word with insurance rep and was informed that he can visit the service station next day it self, however sai service did not have any space to keep my car, so I requested them to let the car get inspected so they can help me remove the water within the car but that was not possible for them. They want the car to have rain water in the car for 2/3 weeks get the car rusty and then fix it. I did speak with an representative from sai service and during the call he just hung up on me.this was difficult to digest... I was still waiting for an representative from sai service to give me his managers number but I guess that's not going to help much..
