i have a phone from onestopphoneshop on a line rental free offer. The document says to send a copy of the invoice on month 4, 8 and 12. i bought the phone near end of november. The billing date for the orange network is the 10th therefore i received my first bill after a fortnight, in dec. Is this bill for month 1? Remember it only covers 2 weeks. If yes then i will send a copy of march's invoice. i rang OSPS and got two answers from two different people. It is the forth bill or 4 months after connection.
