I bought some diving stuff in their shop and unfortunately did not paid attention to the price tags. When I came home and removed them it soon became clear that they do not comply with the bill: 30% difference paid on top.
Some phone calls later I had two different excuses on "how that could happen." Enlightenment was promised to me, but of course nothing has been done. Maybe the management can explain here with a third version. - So be it.
Luckily it was not too much, what have been tricked out of me and I will definitely avoid this place in the future.
Who still wants to leave money here better follows my conclusion: Only with your own calculator.
