Respected people,
greetings of the day,
hope you are doing fine,

Sir i am sending you this mail just to bring this in your notice that i booked hero duet scooty on 20th of october from Hero dealer named "Sangam Automobiles" NH-1A udhampur, j&k, india. During the time of booking the sales girls informed us that there is one offer going on if you booked your scooty now you will get Rs 1500 discount only if you have any government employee in your home and you just give us his government identity plus one copy of ration card with his name on it. And this offer is only the end of this month i.e until 31th of october you can avail this offer.
So Sir i booked hero Duet scooty on 20th of october with the down payment of Rs4000 and i ask them i will come on 30th of october i.e on diwali and i will give rest of the payment with the government identity of my father and a copy of ration card and will take scooty. Till here eveything fine.
And on diwali when i went there for my scooty they informed me that Rs 1500 offer is finished on 26th of october and i can't get that offer. when i asked them that i booked my scooty on 20th and you said me that this offer is until 31th of october and now you saying this offer is finished on 26th how come?
Sir how come this happen? A big company like Hero automobiles which have a good name in india as well as internationaly making wrong promises like this with their customers. This is the second scooty of hero we purchased from the same dealer. And this mail is not only about Rs 1500 offer but i want to know how you guys are dealing with your loyal customers. Even these people not gave me the recipt of Rs 4000 which i pay as a down payment while the booking of scooty. They have the orignal plus carbon copy of that recipt when i ask them to give me the orignal recipt of Rs 4000 as a proof, they said no they can't.
This is the wrost service i have seen in my life. I will never suggest anyone to go for hero scooty. I want the quick response from your side.
if i am sending this mail to wrong address please send it to the concern person.

warm regards
sunil kumar
