Ola Cabs / Ani Technologies — Charging Extra money and returning in form of voucher

I was charged extra money during the trip by the driver and I made a payment through phonepe to the driver. He took a long route other than the route shown in the app which is clearly not my mistake but I ended up paying extra money for nothing . I would not want to use OLA ever again due to all the wonderful experiences I have had and the beautiful customer support experience so this voucher is pointless. I have made a payment through cash so kindly put the money back in my account. I WOULD NOT BE USING OLA TO REDEEM ANY VOUCHER . OLA reps are denying to reverse the charges but insisting me to redeem the voucher and use it .As a customer, Its my choice and i choose not to use OLA again!
