Maruti Suzuki India — Complaint about Ganesh Cars Vellore

I had terrific experience with Ganesh Cars Vellore every year (even this year too - Sep 2021). For each service, they will make a big blunder. It's been 1 month i have done a periodic service and they have not cleaned the interior and AC vent was not working. Driver has noted all the details about the existing complaints but none of that was resolved. Ganesh Cars company doesn't have proper Point of contact, if you ask person 1, he will point to person 2, again he will point to person 3. One of the executive who approached me for the service and for all my complaints is very rude and he don't have any ethics to speak customer (Hemanth - [protected]). He will tell all lame reasons for their mistake and never admit their issues. It's been more than 30 days, still am approaching them for service correction. All i can say about Ganesh Cars is WORST WORST WORST.
