This has happened to me so many times with both flights and hotels. Now I very rarely book through third parties (only search) unless the discounted rate is compelling enough. It just happened to me 2 weeks ago. I booked a resort in Cancun through Chase Travel at a heavily-discounted rate and made an error in booking, for one person versus needing two. Chase said they couldn't change it and to call the resort, their middle agency said they couldn't change it, and the resort said they couldn't change it and to call the agent! It eventually got fixed after hours of calling and essentially pleading.
