Complaint Review: Priceline.com

I made an offer with priceline.com, after they rejected my offer since it was lower than the fair prices, they sent me new offer with a lower price however with 2 connection stops. I was interested in the price, I clicked on the price link to see the itinerary, and there I was commited to buy the ticket, my credit card was charged immediately without having the option to see the itinerary. The major problem is my itinerary, I'm travelling to attend my brother's wedding on Sunday at noon, and they booked my return on Sunday at 7a.m!!!
I tried to contact them, only the automated system picks up. I talked to United airlines they told me to talk to priceline they have nothing to do with it. I sent priceline an email with no repsonse, I paid $700 for me and my wife to attend my brother's wedding they ruined my whole plan, I will only be there for 24 hours. This is so unfair.
