Thank you for posting on the forum and welcome. Apologies for the TV service issues experienced, clearly not the level of service or experience we want any of our customers to have.
Is this something you still require assistance with since your post? If so we're happy to help. Can you confirm which set top box you have? Did rebooting the box resolve the issue even temporarily? Can you ensure all cables are fitted securely in the back of the box for us please.
