Hyundai Motor India — 3rd free service denied

Address:

Kolkata, West Bengal

I had sent my car for my 3rd free service with the service leaflet attached to the service book, but the mohan motors science city workshop denied me free service and asked me to do whatever i can but they will not provide me my 3rd free service. My car is well within warranty and they are denying that. They are forcing me to take paid service. I am well aware of the condition of mohan motors in kolkata but why should the customer face any problem because of that?

This is really not expected from a renowned leading car manufacturing company.
I demand a compensation for the harassment provided.
