LibraBet Casino - Sending promotions and do not add the bonus, now forcing me to wager deposit prior refunding

Dear all,
Over the past few days (included today) I received from the Librabet casinos offers to my account.
I got 3 promotions, they have send to my email, that I can get 80% up to 500 EUR bonuses.

I thought its an good offer, so im gonna deposit to give my luck a try.
I deposited 100 EUR, but the bonus didnt came up to my account. I contacted the support, if they can add the bonus.
They told me, that the management decided just now, to not give the bonus to my account.

I was asking why the casinos is sending promotions to my account, if they know already, that they will not credit any bonus after my deposit to my account.

No answer here and that I will need as well turnover my deposit now.
So, I deposited in the casino of Libra bet to play and I didnt get the bonus + I have to turnover now my deposit.

Thats anything else then fair and highly questionable to do like this to gamblers, if they deposit the money they can afford to play in a casino and at the end you dont even get the bonus and not even get ur own money back u have deposited with to take the promotions offer.
They have offered me free spins to my deposit, what is not the promotion they have offered to me.

I understand if you would tell me that my account is not able to get such promotions but I never get the information from casinos end, so how can I know that?

Please let me withdrawal my deposit or at least give me the promotion u have been offered to my account with 3 emails I get from you.

Best regards
