Housebets withheld promot

I registered at Housebets and participated in a promotional event that required deposits to claim a bonus reward. I successfully completed 2 deposits (0.0085 SOL on 6 October and 0.00899 SOL on 7 October), which fully fulfilled the promotion's requirements.
​However, when attempting to claim the final reward on the claim screen, the system repeatedly threw a fatal error stating: 'Something went wrong. We couldn't load your bonus. Check your connection and try again.'

​I contacted live support multiple times before their promised deadline (8 October at 15:27 UTC). The support agents (including an agent named Brick) acknowledged in the chat logs that both deposits were credited, my wallet proof was verified, the claim was open at its final step, and that the system error was real and documented. Despite this, they failed to credit the bonus manually and repeatedly gave standard template responses, ultimately letting the deadline pass without resolving the issue or allowing me to claim my reward.
​Furthermore, this is clearly a widespread systemic issue, as many other users have also experienced the exact same forced claim errors during this promotion, indicating bad faith on the operator's end.

​I am requesting the casino to manually credit the promised bonus to my account balance as I have fulfilled all conditions, and the failure is entirely on their system's end. I have attached all necessary proofs, including deposit histories, the claim button, system error screenshots, and full live chat logs.
