Error at last step ordering a SIMO

[MikeGFD]

Grrr. Got to the last page of the order process, having entered my bank details and a payment card to be greeted with this:

You can't use this service, or your code limit has been reached.

To continue with your order, you’ll need to go to one of our stores..

Presume the stores are close. Can anyone advise?

Thanks

The stores are closed. Try another browser.

Thanks for that. I don't want to end up with a duplicate order so not keen to try another browser.
