Tata Motors — Tata tiago - average is pathetic

Address:	New Delhi, Delhi, 110012
Website:	Tata Motors

I had purchased a tata tiago in april 2015 basis the advertisements made by the company on the product. Big hoarding were displayed claiming average of the car above 24 km/l, however to my surprise when i started using the car the average was 6-7 km/l then the company officials told me that after 1st servicing the average will increase. Post the servicing the average was 10 km again i approached the comapny officials who told me that once i cross the 2500 km the average will increase however it is only giving 10 km/l. I now assume either the car they have given me is defective or the company has made false promises about the car. Despite several followups with the company i am not getting any response. Kindly do the needful
