It's supposed to be easy to remove it yourself via My Account, @F8C4Y7MB.
It often doesn't work these days, so contact Talktalk directly:

Without it, you'll be paying 24p per minute to ordinary landlines and mobiles.

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 in the post at the top of any forum message board.
