I posted some time ago my dealings with 1and1, their response to my 'mini-gun' like tactics was to detag my name and delete my account.
Whats strange is my account was deleted (oct) a some months before my domain was renewed (feb), then some months after this they detagged (apr), what was going on there I do not know.
Co-incidentally charge-back via your credit card, this really upsets them
