Can't upgrade online not taking payments

[jamieleewv1]

anyone else having issues with upgrades online? I get to checkout to pay the early upgrade fee (£320) but keep getting error message saying there is a problem with system try again later. I've been trying past two days and still won't work. My bank isn't blocking the transaction and I've tried on two different debit cards and both the same. So frustrating 

Live chat won't help they said they can't take payments on their system.
