Uber India — driver forcing me to cancel

Address:

560037

Driver name - ananda, number is either 8059 or 6059, maritime suzuki desire
I was waiting for d cab for nearly 40 minutes and after boarding d cab, the driver asked me my destination and then forced me to cancel it. I asked him that he should have told me before only and why did he wasted my time as i was going to office... Instead he started to threaten me to cancel the ride and so i cancelled the ride. After cancellation i saw i was charged rs. 43.
Why should i give money in this case?
This kind of service and behaviour was not expected by uber
