Scheduled recording

Hi I have had 3 360 but had 2 of them replaced at the weekend so now have one 360 and two of the stream boxes.

Since they have been fitted all our schedules for recording are not working it asks me to subscribe to view them? I believe they are linked to the removed boxes 

I have factory reset the 360 box and it now shows I have 0% recordings but the old schedule recordings are still showing and will not delete.

On my go app it still shows my old 360 boxes so I think these need to be removed off my system.

I have reached out to the call centre but I don't think they understood what I was saying.

Any advice on how to remove the old 360 boxes off the one I still have
