Address:

I had left my vehicle for service in hyundai advaith vasanth nagar. The representative who came to pick my car. I had told him all the things needed to change. But there was no action taken on my request. Just for a oil change n small minor work they have charged me 12k.

I had requested to repair the petrol nob..which was not done

I had request to change the dicky lock which was not done

I had requested to put the alloy wheel logo cab..they said not available

And basic small srew has come out..which that also they have not fixed..

Then why was i been charged 12k..????
