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.

They also let me pay off a little of my device plan the same way too; just not the upload fee

As of the week before last, the remainder of my device plan/airtime comes to £120 thereabouts, I'd pay it off now if I could, but I'd probably have the same problem, and I don't trust the annoying shop staff to not mess me about.

Like one Saturday afternoon last year I literally took my IN DATE British Passport and they still thought I could be flippin' Fred Bloggs!
