Tata Motors — Poor customer service

I planned to buy Nexon. I visited Trivandrum Motors Showroom at bypass road Thiruvanathapuram Kerala 10 days back to book test drive. They agreed to arrange it in one or two days. I waited for almost 1week and didn't get any response. Next week I tried to contact another showroom at Thakaraparamb Thiruvanathapuram. They also agreed the same. Even after 5 days I am not any response from the Tata dealers. Kindly do the needful to make your dealers atleast cater the basic services you offer
