I also used 1and1. I canceled my account, and for the next three years, they continued to charge my credit for hosting I wasn't using or signed up for.
Despite emailing them, and calling them on the phone, each of the three years (and always being told my account had been canceled and they didn't have my info anymore)... I finally had to call the fraud department of my credit card, to get them to stop trying to charge me for services long since canceled.
They provide lousy hosting, frequent down times, ZERO customer service... then, they defraud you.
NEVER use this company!
