Hey @Ri91, this does happen from time to time. The bonuses offered are not a right and as explained will not be offered to every account. As mentioned in the T&Cs:
5.2 Management of the Unibet Account
(i) Unibet reserves the right at its own discretion, and at all times, to:
(vii) suspend and/or cancel the participation of an Account Holder in the games, promotional activities, competitions or other services, whenever Unibet is of the opinion that a Unibet Account is, has been, or may be used for illegal, fraudulent or dishonest practices, commission of Bonus Abuse or otherwise not in accordance with the Unibet Rules;
Unfortunately this block is not something that will get removed.
