The chat support requested proof that the card is not a commercial card.
Also, please take a look at this @anon33247966 [FR] Frais bancaires pour rechargement compte Revolut ??
Looks like a similar issue: gold mastercard, considered as commercial card.
On a side note: I have a regular mastercard with the same bank as this guy, and I have no fees with Revolut.
@anon33247966 Sorry to insist, but will all ING users (who all have gold mastercards) need to provide this proof?
Not trying to be a pain here, just it’s very likely you’ll have to deal with a very high amount of ING users (and apparently other banks) who have personal debit/credit cards and are somehow treated as commercial.
It would be a win-win if you could simply flag these bins as personal cards
