If you're at the end of your contract Hugh, I'd simply cancel them both. I sure upon your return, that you'll be able to wrangle a good deal with a new ISP in your area. And...
Once you have the internet up and running, I'd probably look in to one of the nifty "internet TV" providers, such as Hulu, GoogleChrome, Roku, etc. You'll have a little time to perform some research during your absence from home. It may be worth while to do so.
Something to thing about
