@ekf. Now then. This is the summary. I loaded my card with 3532.95 SEK which was converted to 321.36 EUR. Then I withdrew 200 EUR seeing as a lot of places where I was operate in cash (fair enough). When I checked my balance after the withdrawal which was converted to 2405.63 SEK, I expected to have 121.36 EUR (assuming no ATM fees). What I did find was a neat 67.35 EUR, which not accounting for the 11.95 I spent at a supermarket would amount to 42.06. Actually more than the stated 41.85 but it can be that the exchange was updated since I last checked.
The idiotic thing here is that at no point was I prompted to convert or choose between currencies and the card was clearly detected as a SEK card not a EUR card which it should have been if the EUR currency was chosen. Notice how the game is always rigged and tilted away from the customer.
