Useless Service Delivery

I've booked a vehicle online yesterday foe pickup at 09h00. It's now 09h38 and no one has been able to help me. I see four people in front of me but no one even greeted me. I had to ask for some assistance after being ignored for 10 minutes. I can't believe the service I'm receiving. What's the point of selecting a time for pickup? Thanks for making me miss my meeting Avis.
