Mega Cabs — misbehaving with me and my mother

Dear mega cabs,

I am very upset with your service.
Taday i book a mega cab from harlur road to airport and we have a offer a sum of 750 rupees.
Your driver tell us that you have to pay the bill what meter show. He also misbehaving with me and my mother abuse me and also tell us to get out from my car in the middle of my journey.
Now i am going to tell all my friends and relatives to don't take mega cabs because there drivers are unfriendly there drivers are misbehaving with there customers. When your policy tell us that we only charge rs 750 then why there drivers submit us the bill of 1200 or 1300 or what the meter shows.

I just want to take the appropriate action for the driver. The details are:-

Name :- basavaraju
Car number :- ka 50 a 5995
Id number :- 72015

Regards
