Is there a way the claim of 'having 100,000 clients using us' (perhaps not daily) can be verified? Who is issuing these cards, which prepaid card provider. Can they vouch for how many active cards have been issued in the last years? Anybody who received such a card should have gotten an accompagning letter from the issuer.

If they can't resolve the problems with 1 client (if one looks at how long this drags on), what kind of support are the rest of those 100,000's of customers supposed to count on?
