Uber India — over billing

I have been travelling by uber daily for last few days from kool homes arena balewadi at around 9.30 am to dr nupur physio cure center, vishal nagar 1 aundh wakad road, and back at 12.45 noon to balewadi. Details given below
Date estimated amt billedamt amt paid as demanded by driver
30/1/18 121 121.48 122
30/1/18 65 65.51 66
31/1/18 114 114.20 115
31/1/18 66 66.60 67
01/2/18 104 160.89 161 high billing
01/2/18 75 76.86 77
03/2/18 89 152.66 153 high billing
05/2/18 130 219.67 220 high billing
05/2/18 69 128.44 129 high billing
06/2/18 69 104.01 105 high billing

For the same distance travelled with same traffic i fail to understand the discrepancy between estimated amount and billed amount. This amounts to cheating. Even paise less than 50 are charged as rupee. As a matter of fact 1 paisa is charged as 1 rupee.
Such practice is bound to make uber unpopular.
Please look into the matter and set it right. Feedback on action taken will be appreciated.
