TVS Motor Company — motorbike servicing

Sir, i have given my tvs sport motorbike for servicing bearing reg. No. Ka 03 hf 3559, on 13th july, engine work, verbally they told 9k afterthat, i paid rs. 5k as advance if not the vechicle will not be taken. Since then no phone call till 22nd july. No information until i go check. They told what all spares placed will be given back, but they not maintained any clear details of what is changed no proper documents all verbally. Nothing is written & budgetary estimate is given. Plenty are there i cant keep explaining all this. Till date i have not got back vechicle. Today another 5k being paid. Total 10k. But thereis no clarity. What is the estimate no keeping such a big showroom. Rather i should have done with street garage. This how tvs company runs. I regret to inform. All or cheat in india.
