1xBet Did Not Add My Holiday Bonus After I Topped Up My Account

Some tech bug erased my bonus in the 1xBet app. I topped up my account on September 14 to get the holiday bonus, and while my deposit went through, the bonus did not. I really hope someone can explain and help me with the bonus that the company promised, because it seems they never gave it to me. I don’t see it in my account 1905739***, even though I definitely received the bonus notification and also have it in my email inbox. But in the app, there are no bonuses showing on my account. Please give me back my bonus!
