Now I see where the whole problem is coming from, because I just read the entire conversation on this thread and at this point could conclude that O.P is to be blamed why his account is yet to be unlocked. Because I noticed he was given a simple instruction to send a mail through his official email address linked to the account he was requesting to be unlocked, which is "Support@bspin.io", but yet he went about sending a email from a different email address, which is "bspin@bspin.com", which might have created an iota of doubt on whoever could have been investing that case. And as such, I will advise O.P to please send a mail from the support mail which is "Support@bspin.io" and also drop a screenshot here, so that everyone could be able to see that you truly have access to the original email linked to the casino and the account you are seeking to be unlocked. Thanks. Wishing you all the best of luck.

Just a guess:
Maybe, you didn't get any response from the recovery team, because you didn't send the email from the email address used for registering that bitcointalk account.

Assume that a company has an account here in bitcointalk and the recovery team accept any email sent from their website domain as a proof of ownership.
What if each of employees of the company has an email address with the website domain? Then all employees can recover the account.

OP hasn't been able to prove his ownership over the account for more than 5 years. He (or someone else?) posted a similar topic in 2020 using another account and there was no success.
Maybe, OP didn't have access to the email address used for the locked account and he sent the email from a different email address.
