Creditcard is one that I need to pay every month, so that one will only be used in the end (probably) for the daily costs of the travel. I don't want to use more of that card than I need to..

That's great that you got lucky, we have been thinking we were lucky for more than a year now when it comes to Dutch taxes (re-calculations from several years in our favor) but so far every time we have received a letter with you get x back (a lot!), it's always been swiped away afterwards .. so then suddenly there was another thing unpaid .. we have been going back and forward with them since last year, and I still have hope the outcome will be my road to steemfest :)

Can't lose hope and faith :)
