This complaint is regarding the pathetic service provided by the deedi motors trivandrum. I have been affected by their poor quality service for the second time now.
It seems when we take our vehicle to them for service, they have a predefined budget in their mind, which they have to bill for us. For doing so, they say that following xyz component is not working or is damaged, it needs to be repaired else vehicle wont be functioning smoothly.
In my case, i went to them with a problem that whenever my car rolls above a speed breaker, a sound can be heard from the front left tire part. After delivering my vehicle i got a call from service associate that, shock absorber is damaged and needs to be changed for the issue and total amount will be around 12k for the entire service.
But even after the service i can still hear the same sound, when i called them they said there is no other issue from the car and also they haven't heard any sound.
Also after the service, battery started developing issues, the vehicle take almost 5-10 minutes to get started. On calling them they said to replace the battery which again took around 6.5k. I said that after service this issue started, but they refused.
This is really unprofessional behavior from their side. They will never listen to customer issue, they will fix a budget and ask us to pay that amount.
I have decided one thing, i will never ever give my vehicle to any chevrolet center, as i don't trust them. They only know how to loot people.
