They took advance and didn't provided the service. We have been calling customer care and salesman for 3-4 hours everyday. They are reluctant to solve our problem. They register our issue and mark it resolve without doing anything. We have tried reaching their senior officer but we are unable to do so because o[censored]navailability.
We are severely disappointed with the service and feel cheated.

Kindly help us with the issue. We want some penal provisions against them and ensure their accountability.
