S V Motors Bosch Express Car Service

I had a WORST experience with S V Motors Bosch Express Car Service Hitech City. They simply cheat people. The discriminate customers who approach them with coupons (frm nearbuy etc.) vs a regular customer who goes to them for a normal service (without using coupon). If you call them and enquire at what time the shop opens, they say 9:30 AM. But the moment you say we want to avail the coupon they say that they will open at 11 AM and they also say that there are many vehicles for services on that day. I went to them twice with the same bitter experience. In fact I called them before going to the service center, they confirmed that they are available to do the service. But after I went there (almost 14 KM frm whr I stay) and after telling that I want to use coupon, they said that I have to wait till 5pm.

Please don't go there and be looked down. Keep up your self respect.
