Uber India — unprofessional behaviour of the uber driver

Address:

Pune, Maharashtra

I booked my uber ride on dec 12th at 10.11pm from law college road pune to azad nagar pune - driver chaitanya tata indica mh12nx1037... Mob no.[protected]. He called me and asked me where i wanted to be dropped and said he would arrive in 5 mins, i waited for 30 mins calling him every 5 mins but his phone was switched off. He did not arrive nor cancel the ride. I had to call an ola to take me home.
1. Y is there no number to call when your drivers behave like this?
2. How come i have to pay a cancellation fee when your driver has defaulted?
3. While booking my uber the amount shown to me was rs.251/-, after reaching my destination i had to pay rs.315/- why? Please explain this increased amt in my fare.
