These people loot you in broad daylight. I gave my Honda Activa for service. I became suspicious after two people quoted different rates for same services.
The second person was too blatant and was clearly trying to fool me by suggesting useless services and part replacements that were not required. I raised a red flag when he said 50 rupees for filling air in my tyres. I said air filling is done for free.
The worst part of this experience was still to follow. After paying around 1400 rupees for basic service, these scamsters replaced my rear tyre tube with a punctured one, and on my way back to home I almost met an accident because of the punctured tyres. I am still fighting with them to get my vehicle in the condition in which I handed it over. These people are SCAMSTERS. They need to be taught a lesson.
