@jamie92: It sounds like you're on the right track with your claim, but did the Promotions Team specify what information was missing from your proof of purchase? If they did, try reaching out to Sky to request a document containing all the relevant information requested by the team, and you should be good to go. Usually, valid proof of purchase should contain the retailer logo, reference to the phone, the amount paid and the date of purchase, preferably in a single document.
I never received an email asking for the information they wanted. my second claim I sent everything I could so fingers crossed
