Have you recently switched to Fibre to the premises?
If so, then I had a similar issue as My Account has not caught up with the change in package and was trying to test my old line which had been switched off.
I caught up eventually but I could still get my speeds by using something like Ookla.
If no, then I'll leave it for staff to investigate further.
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here:
