I am not trying to be negative here but base on your statements, there is a big possibility that the team behind goosebet.io is in the process of leaving the platform and running all the money also.

No response, no support to answer the queries and admin are missing for a week already. These are the signs for sure that they are are starting or already abandoning the platform so there is a very low chance that those pending withdrawals will not be processed, not only if I am mistaken.
