Payment went through but no booking confirmation for the car rental

I did a booking last night on eBucks for a car rental . The payment went through my account but I didn’t receive a booking confirmation. I just spoke with eBucks now and they are telling me the money is pending it can reverse but they don’t know when and to whom it will reverse to . Me or them . So now my question is how am I going to pay for another booking if my money is with them . And when will I get the car or how coz I want it for tomorrow. This is not the first time I’m having a problem with this booking engine it’s useless
