You paid what!!!
What prep was done before laying? Is the site quite shady? Those two things have an influence.
They shouldn't have told you to feed it so soon either. Plenty of water if you don't get some serious rain over the next few weeks. Do you have a hose, even if you don't have a sprinkler? If so, you can prop it/tie it up through the handle of a fork pushed into the soil, and leave it one for an hour or so. If you don't have a hose, that's going to be hard work watering unfortunately.
I have to admit, I'd be pretty hacked off if I'd paid that amount to get that result. Don't worry though - if you water it enough, it'll recover, and even if it looks a bit rubbish, it can be sorted with a bit of soil and grass seed later on.
