Ola — Payment paid to driver but still showing my app pending payment

Address:

Chennai

Sir,
I am receiving call from ola about ola postpaid pending but i paid cash to the driver while droping there is no pending from my side but i am receiving regular calls and msg form ola. When attending calls that was system voice and no option to contact anyone. I tried customer care no one picked call and mailed to customer support then no response for that. Now I am receiving threatening message that I am not responding ola so we r file case for that and also affect cibil score. Kindly clarify me who had mistake and solve me this issue.. my mail id [protected]@gmail.com and my contact [protected]
