Priceline complaint: HORRIBLE CUSTOMER SERVICE

I am COMPLETELY disgusted!!!! I reserved a vehicle for the 13-15 of October thru Priceline. The only reason I even needed the vehicle is because my Tahoe was stolen 3 weeks ago. My reservation was for 5:30 due to scheduling and others work schedule. I called the local number at 5:24 to say that I was 9 miles away and would be less than 10 mins late. The agent noted the account and also contacted the Lawrenceville Hertz. Everything was approved and I like others have a 30 min window. When I arrived after ation, I was dropped off to get my vehicle and the location was closed. I spent over an hour going back and forth with agents even approving the 5% hold that they require for a live agent to be told, OH WELL, call them tomorrow. A single mom stranded in a neighboring town, with no ride and no way home was very upsetting. I missed work and the list goes on. Not to mention, I AM STILL WITH NO RENTAL
