Here's what you do in all of these situations with big companies where you get mysteriously banned and can't get any recourse from customer service: find a mailing address for their legal department and send them a letter return receipt requested (or whatever the equivalent is for where you are in which you get a receipt from the postal service confirming that the letter was delivered). In this letter, you politely but directly lay out the facts, indicate that you are not in violation of their terms of service or any other legal document, and tell them that you would like the money you are owed, as well as to have your account reinstated. Inform them (again, politely but clearly) that if you they do not at a minimum send you the money you are owed, that you will pursue appropriate legal action. You don't need to specify what legal action - just appropriate legal action. Since it's 150 Euros, unless you've really done something wrong that would lead them to get in trouble if they pay it out, they'll almost certainly just pay it out. There have been a few examples of this on HN (none of which I can currently find, unfortunately) - person sends appropriately written letter to legal, legal understands that this is not worth the time and the best resolution for the company is to comply, company complies. Good luck!
