Hi Wesleymcuk​
Sorry to see you are having problems with your 360 boxes.
Normally VM systems won't allow an engineer to be sent out if there are problems in the area, or if one has been requested and then an area issue becomes known then the appointment is automatically cancelled by the system.
Have you used the /check-services/ function for any problems in your area? You can also a run a test on your equipment from there.
If nothing is showing you could also try the automated Service Status number 0800 561 0061. This is generally better as it gives details of more local issues down to postcode level.
What are you seeing on your 360 boxes?
A totally blank screen?
A screen with Welcome in different languages?
A screen showing an animated arrow and floppy disk?
A screen with an error message and code, for example CS1020 TV box was unable to download a software update.
There's a list of error codes and possible solutions
