Whoever supplied the turf gave you a dud lot!. Treat with the nematodes first, they will take a while to work, 2 weeks after treatment, you can resow the affected patches.
The lawn won't establish properly till next spring /summer, so be patient. If it's still looking ragged in spring, scarify the affected patches and resow them. Lawns are a lot of work and quality of turf can make a huge difference. Your's doesn't sound to be too great, so I'd whinge like hell at whoever sold it too you.
