Ola Cabs — Ola cabs cheating in billing

Address:	Hyderabad, Andhra Pradesh
Website:	OLA CAB

Sir,
On 26th april 2016 i booked a cab from rgia hyd. To bhel hyd. Pick up time was 11:00 pm. I got driver and cab detail in 10 min. Advance, but when i called the driver, he did not answer my call. Then called ola hyd. Ola hyd. Asked me to cancel the current booking and make a fresh booking. On fresh booking, i got a call from ola driver. Since it was late night so i did not bother to go through the sms sent by ola. At the end of journey i was charged 1.8 times the normal rate. Driver says, pl. Read sms. It is clearly mentioned that you will be charged 1.8 times.
My complain is once ola cab was available on airport, why ola management asked me to cancel and do the fresh booking and why i was charged 1.8 times.
