They refuse with my refund as I previously loaded money as a Driver.

I was previously a diver and I loaded money on the App. However I'm no longer a driver and I no longer have a vehicle. So I have been requesting for refund for over 3 weeks sending several requests but all they do is just close my case. I want my money either as a voucher for me to request rides using it or paid back to me. I have sent all the information they required but not even one feedback they just close the case. I want my money back.
