Mahindra Two Wheelers — Servicing and Customer Attending

Address:

395017

I'm Vijay Painter ([protected]) having Mahindra Centuro Registration no: GJ-5 MN 2504 (Surat RTO).
Here in Surat, I think only P B Auto is looking after Sales N Servicing of two wheelers and for the same, they are not taking proper care of bike servicing and behaving with customers very rudely.
I always give my bike for servicing here, as local auto repairers are not capable of repairing it. Today morning while repairing puncture, i found Left Jumper Resting Axle's Bolt is missing; it means either it was not fitted or loosely fitted on previous service, some 4 months ago. and it could have a big accident if jumper come out of axle.
Not only to these extent, on payment time, I have already mentioned that I do not have cash of Rs.985, and shown them ATM's empty money reciept of today's date, and I was having only Rs 700 in cash, but i could pay by Paytm or Debit/Credit Card money transfer, but they cleanly denied to transact through cash-less and rudely told me to go back and come back with full cash money, and only then Bike would be delivered. and at last they received 285 by Paytm and hand over my bike, but without Bill.
I want to know, is this the way to treat with a customer and harass him?
