Uber India — payment deduction against cancelled booking

Address:

Mumbai City, Maharashtra

Today on 31st may 2018, around 10.05 am i booked cab & got confirmation that hyundai xcent (Driver name jagadeesh gaddikeri) will report to me within 18 minutes.

Within minutes, i get another message that cab will report to me around 10.55 am, that is post 55 minutes of the booking.

Seeing this message, i cancelled the booking for which uber deducted rs.76.15, with 1.4 times surge pricing, from my paytm account linked with uber.

My questions are :

1. Is it that uber app deliberately show lower reporting time so that customer remained engaged to wait for the cab?
2. Is it that through such means uber enhance their earning by deducting fare charges from customers?
3. Can you build up or retain your loyal customer base through such business practices?
4. Seeing such business practice, why should not i delete uber app from my mobile & say never to ride again in uber?

I expect uber not only to reimburse deducted amount to me but desist from such business practices by correcting such glitches of huge variance in actual reporting time & conveyed reporting time of your cab
