Rang my mobile, didn't leave a message. Just had several calls from various numbers, the first one from nbnco. After 20 minutes on that one, I hung up. Man with Indian accent, said I would get a new modem, but when he said I would need to pay a small amount by credit card, and wanted the number on the card, I refused. Very insistent, but didn't trust anybody with my credit number unless I'd rung them.
