Unfortunately my remote is no longer working and your call centres are so busy that I can't get hold of anyone. Please could you kindly send me a new remote.
You could try the text messaging service.
Just send a text with a description of new remote to 07533 051809. Your message will go into a queue and a representative will respond to you as soon as possible. It may take a few days.
For now you could download the TV Control app and use that until you receive a replacement remote
If you do decide to phone you need the TV Faults option when dialling 150
