Here’s a revised version of your text with improved clarity and grammar:
I fell off my bike because the back wheel was not tightened properly after I got it serviced at Vijai Auto Bike TVS in Chidambaram. The bolt from the wheel came off. When we approached them about the issue, they handled it unprofessionally. Two days after the service, they questioned how they could be responsible for it, even though I hadn’t used the bike since the service.
Eventually, they came to my place to fix the issue but insisted that I should have kept the bike at the spot where I fell. However, I had already requested them to deliver it to my place. This incident reflects their lack of care and humanity. Due to their negligence, I sustained injuries to my leg and hand.
