Thanks for your help.
Well, he asked for bank account number, but then i didn t give it to him . So then he asks for debit card No., should i give it to him.'cause he says he needs it to operate his computer system for register an account.
sympatico requires such info, so do some other service providers. Don't worry about it. You won't be registered if you don't authorize them to charge you from either your banking account or credit card.
