Casino Slotsmillion 150% bonus up to EUR 300

Hi guys,

Today I received a bonus offer from slotsmillion.com with a 150% bonus up to 300. I checked the wagering requirements and it says x 50. So i want to live chat and asked if the wagering requirements were 50xd+b, 50 x b or 50 x d. I got this suprising answer:

are depositing and you are winning in your real money, than you have to
wager the amount that you have been depositing before you can make a
withdrawal with the real money and cancel the bonus. If you don't win
with your real money than you have to start wagering the bonus money 50
times. And when that has been completed, than you can request a
withdrawal on the wins with the bonus money.

I've asked if she was sure about that and if she could mail the conversation to me. She than says:

SlotsMillion. You just have to wager your real money 2 times.

What do you guys think about these wagering requirements? Anyone here have experience with the wagering requirements at slotsmillion.com?
