Ola Cabs / Ani Technologies — ola outstation charged double the actual rate

I have travelled from bangalore to ramanagara and the distance travelled 2 ways is max 120kms. My only mistake is that i didnt note the kms reading before and after the ride and blindly trusted the driver. Later found out that driver recorded 242 kms and so i was charged extra. Ola support says that their system shows its true but i have travelled to the same destination many times before and know the distance of the route. Driver has switched off his number and ola says their system says i travelled extra.
