To,
The respected sir/madam,
Iam srinivas, the main reason to write the letter, is to tell you regarding the bike engine struck problem. We have purchased a bike in krishnasai motors (Maestro ts 08 fx 1229) in the month of october, 2017. Assuring 5 years of engine warranty. But from the beginning itself it has given us trouble.
We have given first 2 years servicing in your servicing center itself. After that i gave servicing outside (Local service) because it was out of station. Recently, 2 weeks back i have given bike servicing to you.
While we have given servicing after local service, you have taken up servicing for bike but why didn't you inform us regarding the engine struck problem?
Before 3 years, how can this engine struck trouble occur. For what you have given us a 5 years warranty. So, solve our bike problem in the warranty period. If not legal action may be taken.
So, i request you to solve our problem as soon as possible in the warranty period.
