I had some bad experiences with Maruti Link (Maruli authorised service dealer in Salt Lake, Kolkata) which I wanted to share. I am not expecting that someone would take action, but to caution customers specifically staying in Salt Lake / Newtown area so that they are aware.
My car recently met with an accident. I took an estimate from them and they repaired the car post approval from the insurance company. I "explicitly" told not to repair one of the doors, whose repair cost was not approved by the insurance company. Despite that they went ahead and repaired. Hence I had to pay money out of my own pocket for the repair of this door.
This was not a new "shock" for me as it was my mistake that I trusted someone where customers don't want to go again. in the past I remember that once I gave them my car for services and they tended to add other parts which are usually not required and made me pay for this. I thought these were genuinely required, but on alter opinion of my friends I realised that this is a very common practise at Maruti Link. Despite its monopoply in the radius of 10-15 kms it has not able to retain its customers because of its bad business practices.
