i want to make payment through prepaid card, but i am not sure if pknic register .com domain or they only .pk domains?
No! the sell only national TLDs to domain resellers or directly to users. They are the registry holders for .pk domains.
Choose some other cheap domain registrar. A wide range of registrars have already been discussed on WP forums, you probably should know that.
