Website error from Member Centre page

[#1]

Just tried a few times to click the Product Change tab, after a short pause I get the following :

Error
Sorry, An error occurred whilst processing your request.
The error has been recorded and our website team will investigate. Please try again later.
I just wanted to see if i can add anytime calls to my package and if so how much is it, or do i have to wait until I'm out of my 9 month lower price deal first?
Thanks
PS: Just noticed my router as well: Uptime: 43 days, 13:54:50 I think BT were lucky to manage 10 days

We're looking into this issue now, hopefully the product change link will be working again shortly!

Thanks for letting me know, I was just coming back to ask if you could try it again!
