'Please try after some time.' message when trying to redeem reward card

[thebarnerd]

Hi, I've received my email several weeks ago to redeem my BT reward card but every time I click through the process I get this  Error, 'Please try after some time.' . This has now been happening for several weeks, can anyone assist?
Thanks
