I vipin deshpande booked a Xcent SX cng form modi hyundai on 28.12.2015 . and take a car delivery on 14.01.2016 on request and mutual understanding that the said CNG part is not available from their end hence the said part is being fitted with in 2 days.
but since daily follow up with sales team till i not get commitment for when i will get CNG unit is fitted in my car.
daily i have running of 80 km and hence since last 11 days i m running on petrol which is not profitable for me.
very disappointed for that no one give me the commitment for the said issue.also phone calls also not receiving by sales persons as well as customer care manager.
