Keeping more than five underlying cards after upgrade to Curve X

I have asked this question, support eventually responded 6 days later after numerous secure messages, but failed to answer the question of whether they will honour the cards I currently have if I upgrade to Curve X which now has a limit of 5 cards.

If the answer is no, I will cancel my card as most of my purchases now are done via my mobile phone and google allows multiple cards, granted it doesn’t have the feature go back in time but I can live without it for the limit and additional cost. I would be happy to pay £1.99 if they will allow my existing cards to be ported to Curve X.

I will update you all once i have received a response.

I think this was answered in another thread. The answer was no, you can’t keep more cards, even if you have them already.
