I am awaitjng my 4th bill scheduled for end of next week so that I can invoice for my first round of cash back on my contract mobile. It was a clearance deal so I have only 21days from the bill date to get it in. As the bill usually arrives 3 or 4 days after the printed date its tight anyway. If the strike causes me to recieve the bill late or arrive late then I'm sure I won't get any sympathy from the Mobile retailer. This will mean I will lose all £480 (12 months free on 12 month contract) Will I be able to recover this money from Royal Mail as compensation?
