Be careful when you rent from these guys

This is not the first incident I've with this rental company. When you take the rental cars the petrol tank is not full but they demand that when you return the vehicle the tank must be full.<br> <br> Latest incident 16/07/2015:<br> We rented a vehicle and 100 km into our trip the tank was half empty. which all of us were shocked because we all have cars and there is no way that any car would be half empty in 100 km on a downhill stretch of road. No mater how old the car was worse it was a Polo Vivo which is very petrol efficient.<br> <br> We returned the car with the same amount of petrol that we received at and more and they want to charge us for not filling up a car.<br> <br> Thrifty is very Shifty, so disgusted. Never using them again including all my friends, family and employees.
