Upgrade, fraud error, wont let me pay 4.99 delivery fee

[Clars]

Been trying to upgrade for weeks, I get stuck and customer services also on the pay delivery fee, keep telling me it won't go through due to fraud error, I have tried 3 different banks all registered in my name and address same as my three bill. All come up with same fraud error. Three tell me it's the bank, what 3 separate accounts that have no blocks on, confirmed by banks that no payment even reaches them, they tell me it's three.  Been online chat over 4 hours, passed all over the place and still no help.

Hi there, Clars. 

Welcome to the Three Community. 

That sounds really frustrating and quite strange as I have no idea why that would be happening to all of your payment options. I don't know if this is an option for you, but have you considered or tried doing it in a Three store instead? I'm wondering if they would have success with taking the payment directly. 

Pete.

I am having this exact same issue and cannot go to a three store as there is not one within an hours drive of me and I do not drive so impossible to get to a store which is why i do upgrades online. So far 3 calls with complaints dept and now waiting another 48 hours for another call back. The issue clearly lies with three as confirmed by all my banks and also someone at three and yet for some reason the "fraud screening" issue cannot just be removed from the account, i note the money for my current contract is having no problem being taken!
