Got Scammed, Help Needed

I don't know it's the Correct sub or not for posting this but any help will be much appreciated.

I tried to Book Ola Cab from Bangalore Airport, and one guy took my bag and told me it's Ola Prime Plus, and I need to Cancel and add my Name and Ola Phone number in his app and it will be a direct trip, as taking the Car inside Parking wastes more Patrol he parked outside and I'll have to pay Prime Plus fare only, which was 800 and after discount 700. But when I reached the Price he showed was 1800 as I started arguing he said I have to check with Ola after paying, or he'll take me back to Airport and check there, the App he used to generate the bill was called bluemeter, which is not Ola App, so there won't be any point of getting in contact with them. After 30 minutes of arguments, he forced me to pay 1500. I payed via Gpay Icici Upi.

I have applied for fraud transaction through imobile app and now I can't open the imobile app anymore, it's saying Access to iMobile is currently blocked on this device.
