Just not Avis PHL. I've had 3 rentals with them in the last 4 months that were never checked-in upon return (agent said they'd email the receipt due to long lines, handheld computer not working etc). All three took over two weeks past return to be closed and two took over a month. In each case, I had to call the CHM desk or speak to a manager at PHL during another visit to have them closed. They all took my word on return date. At one point, I had 3 contracts open with Avis PHL at the same time (2 were old ones that were never closed, plus the car I was currently in). I thought for sure they'd catch it/say something but never did.
