After realizing this was a poor argument to make, they said I only requested a permanent self casino ban and not a self exclusion.
As far as I understand, you didn't want the self exclusion from stake coz you wanted to bet on sports section of theirs.
But you lost the said amount on their casino section post revocation of the "permanent casino ban".
If that's the case, the ban shouldn't have been rescinded that easily with just a simple message.
