Unable to remove email from account

Hello,

My personal email address is bound to my mothers Virgin Media account - when trying to remove this online and after recieving the verification link I get an error along the lines of "This link is no longer valid" though I have just recieved it.

My problem is that I have just got Virgin Media at my own property but now I cannot access my account with my email address because its bound to the wrong account.. 

Can someone help me please=?

Thanks
