I suspect agents are very busy dealing with queries arising from this change. Have you tried Live Chat? Other than that the team here can sort this for you if you would prefer.
Many thanks for the prompt reply. I have tried phoning and live chat but to no avail. I would really appreciate it if you could help.
I can opt you out of the upcoming TV charge but I'll need to confirm some security details to access your account. I'll send a PM separately with the info required.
Please note however that when you opt out of TalkTalk TV you will lose access to add and remove TV Boosts flexibly. You will lose access to TV Boost on demand content via the TalkTalk player. You will also lose access to TV on the go services via the web and Mobile App.
Also, any current recordings you have made from a Boost channel will stop working when you are no longer subscribed to that channel.
