I picked up the vehicle with 510 KM (photo taken) left on the tank, which was deemed to be full based on the throttle (which we know can stay on full for several kms). When I filled up prior to return it registered almost 730 KM, which indicated that I was not given the vehicle with a full tank. In fact, I was paying for about 40% more fuel than I actually used. I raised my concern with the attendant, asking for an appropriate credit amount for the fuel surplus, and she said there is nothing that can be done. I am now reluctant to rent again from Discount as this is not an honest practice. Disappointing to say the least.
