Used the 10 euro no deposit registration bonus. Won 700+ with it, deposited 10 to unlock the 100 that I could actually withdraw.
Started the withdrawal on the 13th of April. It's now the 22th and it's still on waiting authorisation in my account.
Contacted customer service 3 times, the are nice and helpful, saying that they will look into this and sort it out.
But unfortunately nothing is happening.
