Travelex supercard problem

Usually_puzzled

Thanks to this site for telling me that I can get cashback on credit cards linked to my Supercard, I have tried to add a card. a John Lewis Partnercard (it's a Mastercard and so permitted). When I click on "Add a card", I get the usual message about contacting my bank. But when I hit "Continue", I get a screen message, for a couple of seconds so cannot read it, which refers to the XML file not having something associated with it and a lot of code. Then it just doesn't verify with a "We're still waiting on verification.....so check back in 2 minutes". Nothing happens so I remove the card and re-add it with the same result. I've added another card and then removed and re-added my main card - so is it just John Lewis? Any advice?

OOOO

hey, at least you got a card. I phoned them a week ago to ask about waiting times to receive a card, was told two weeks max. so applied then received 'sorry there is a delay' email.
turns out they are unable to process any applications. but you only find that out after you have applied.
Hope you get your problem sorted though

Sorry to hear about your woes, OOOO. Yep, my card arrived in a few days but I was leaving quite a bit of time before my trip [insert a smug smiley face here!].]

In the absence of replies, I've been reflecting over the week-end. Is it that store cards as opposed to bank cards are not allowed? The 2 cards I have registered are a Metro (the trip is outside Europe before that prompts anyone to ask why I'm worrying with a Supercard at all) and an M&S card - M&S may be a store but it's also a bank (I think).

But it would be nice to get some authoritative view. I only get 0.25% cashback on M&S as opposed to 0.5% on my John Lewis.
