@harryclarke As long as you have now reached the activation date, you will need to call SKY and report that the ONT was removed by someone, they will arrange with OR to have it replaced and will advise you of how long it will take when they give you the appointment time/date.
If you haven't got a current Sky Mobile or Sky Talk this link should help:
(UK) https://www.sky.com/help/home Scroll down and click on ‘Need more help’ and it provides a 0333 number
(ROI) on the same link change the flag in the very bottom corner to the ROI flag to obtain an 0818 number.
Stay on the line and don’t hang up if prompted to. Apparently the quieter times to ring are just after 7am or about 9pm.
