Horrible Service

I recently rented a vehicle from Tempest/ Europcar. When I picked it up I realised that the vehicle had not been filled up (petrol). I took pictures and shared these with them. I also shared this with the OR Tambo Branch when i returned the vehicle. To date, they have ignored me on this. This is annoying because if the table were turned and i had returned a vehicle that is not full, i would have been charged. I have sent several emails and have had no help. Horrible service and will definetly not be using them again.
