We were due to drop our car off at Melbourne airport but due to terrible lack of signage we almost missed it. There were no signs for where to return vehicles and after circling the airport several times, we telephoned budget. As it was after opening time, I expected someone to have answered, but unfortunately nobody did. We telephoned several times with no answer, which of course added to the stress of trying to return the car. After eventually finding the location and returning the car, the staff member who greeted us to check the car over told us the company was unable to display signage detailing returns due to airport rules, which is ridiculous. I understand the company has little control over airport signage,however the fact nobody responded to several phone calls was highly frustrating and added to our stress greatly. We arrived at check in less than five minutes before it closed, not a nice way to end a holiday. I returned the car three days ago and have yet to be emailed my invoice, another example of terrible communication. Would not recommend.
