1xBet New User Bonus Issue

I registered with 1Xbet hoping to take advantage of the bonuses offered to me. I top up my balance by 300 USDT at 15th of May. But when it was time to take bonus, I discovered that I dont have any. I carefully read the terms and conditions, but did not violate anything. I tried to contact 1xBet support service, but unfortunately they could not explain why my bonuses were missing, and this upset me very much. The thing is, I had great plans for these funds.
