there cpanel and everything is weird.. but if you can get past that and don't plan to ever cancel then you'll be ok.
I tried to cancel and went through 4 or 5 pages on cancel.1and1.com and when i got to the last part.. the submit button took me to a not responding page.. i emailed support and they waited until after my billing date to respond but still told me to goto cancel.1and1.com to cancel it.. i had tried with chrome, firefox, and IE.. I responded again and I guess they "fixed" it.. because i finally got it to work.. so i got it canceled finally and they said I owed them 6$ since I didn't cancel before my billing period.. and sent me off to collections when i refused to pay since I had sent them an email prior to my billing date.
