Getting what I paid for from 1&1

I do all my own web hosting on a dedicated server and control all my own DNS setting so for the most part I never cared to much on who I purchased my domains from. When I first started purchasing domains, way back when I added one image to a website and I thought I was the best designer ever, it was from Network Solutions. Since I have always provided my own hosting paying that much for a domain did not make much sense. So I started purchasing domains through godaddy.com for $10.00 a domain. Then a friend had me do some work on his site and he was getting hosting through 1&1. Since they were 10% cheaper, yeah its only a buck, I thought it would be a good idea to move all my domains to them. When I moved this domain monekyoncode.com to 1&1 to start this blog, I thought what can go wrong because I do my domain lookups and hosting. Well they still set up the DNS to forward lookups to your DNS server and apparently they screwed that up. The best thing about this is after only having my blog up for 3 days it was down for close to a month as they continually  just reset the domain and it would fail time and time again. So what leverage do I have over them, do you tell them "Fix it or I am taking my $9.00 someplace else." Well as you can see the blog is back up but I am still unable to do my own DNS lookups.
