Ola Cabs / Ani Technologies — Mode of Payment Automatically Changed after ride completion and I was charged Twice - Cash & Postpaid

I booked the ride on 12th Feb, 2022 at night around 9:30am, with cash on completion. The CRN number is [protected], from Ghaziabad to Delhi (near JBM school).
After the ride got over, the driver was shown the amount Rs.739 due (on-screen) and we paid Rs. 739/- in cash. After 10 minutes, I got a message that my postpaid account is deducted as well.
I have done multiple complaints but every time being routed to another department (postpaid/olamoney/support etc). Have tried raining this issue but no one is responding correctly to solve this issue.

His technical glitch because of Ola is hampering me.
