They have to wait for us to deposit until the expired date.
Just checked and yes, it says
Until October 28, 2020. Thanks for the reply

I just logged in as well and open the Bonus page but there is only one bonus under the ALL tab which is about Cybercup promo as shown
http://prntscr.com/t7wtrn that's because you haven't activated the bonus. You need to go to the Boost promo page and click where it says
Activate bonus!, it'll take you to the bonuses page, the promo code "BOOST" should automatically appear there, then you just click Submit and done, the promo will be active (:
