Hi my V6 box keeps restarting itself and hangs at the welcome screen. Once I get it on the recordings are missing big sections and the box itself freezes. I think the issue is with the V6 box. How do I go about getting this fixed as I have tried the chat in the mobile app and have not had a response or I get a response and then the next day I get a question asking if this is all sorted when nothing has been discussed. Any help would be very much appreciated.
