Do not use the online shopping channels unless you have a contract. I received no proof of purchase and could not cancel the order as I was not a customer. The item arrived after 2 months waiting. I tried to return it but it took weeks before O2 sent me a return address. It was sent registered and it was not signed for (Royal Mail offered to refund me). With no proof of purchase Royal Mail could not help. O2 failed to give me the proof after weeks of asking. Finally I was offered to refund but it did not happen. After days on the phone I am still £199 out of pocket + repeated trips into town with proof of ID to the O2 shop and many calls to pay for. Shocking DO NOT USE THE ONLINE SALES.
