Ola Cabs / Ani Technologies — payment already made

Address:

Noida, Uttar Pradesh, Gautam Buddh Nagar, Uttar Pradesh, 201307

On 12 th april 2019, i have booked a mini white wagonr crn[protected] from shatabdi vihar sector 61 noida to igi airport at 5pm. Amount was 630/- and we made the payment to the driver joginder in cash. But now its coming in app that it was postpaid payment and the payment amount of 630/- is due. When we have already made the payment in cash to the driver, why do we have to makeup the payment again. Is it that driver has tricked us and took the payment in cash although the payment mode was postpaid.
Kindly help in this regard. Thanks
