This is yashwant beeram ([protected]). I buyed tvs scooty pep+ in april 2016. Recognized owner is b. Swarna latha (My mother). We gave regular services till 2017 january in tvs service show room. Due to personal reason we gave next 2 servicing outside (April and july).
We found some engine different voice 3 weeks before. So we took the bike to tvs show room. They said engine got break down. So need to fix new engine. It costs around 6000 rs. I asked regarding 2 yrs engine warranty. Tvs show room said as you gave 2 times outside so they cannot provide engine waranty. Its really hard to digest in 1 1/2 year engine got break down.
