Ola cab delhi NCR - I booked a cab for my friends and they paid by cash while ola show pending at my account

I booked a cab for my friend at last night with option paid by cash and I also tell this to cab driver and cab driver say to me he is known very well to my friend and both they are from one colony and he will recived there bill by cash. And after booking one day later I want to booked another ola for me and I found there are show **** rs for this ride when I call driver and ask why you dropped him without taking your bill and drive was for a cash on payment he reply me your frnds say to me that you have lots of money and to this trip as pending while Maine friends told me he all ready paid this amount to cab driver as a cash a payment. So I have too many objection about this -*. When I booked a cash on payment mode why cab driver dropped without charge there bill.
*.if my frnds not paid then why not driver call me at the time of dropped.
*. Why cab driver not go for police if he not get there payment.
Why cab driver convet a paid cash bill in to a pending.
I think driver is found froud becouse if my frnds not pay him why he doesn't any call to me at that particular time.
