I have NEVER had a problem, not with paid accounts, not with the free accounts.
FYI- the free accounts need to be accessed every 2 weeks or the account will be closed after the 3rd week.
The only way to save it (if u have important info u dont want to lose) is send in a payment to change it to a paid account. CYBER keeps all your account information, files, saved messages, address list and whatever else saved for 6 months. If u dont change your account to paid status by then, THEN everything gets deleted for good.
