what makes your issue worse is that you requested a permanent exclusion to the other 2 two account you opened before
i closed this account before i opened the new one, so I think it should not makes my issue worse i hope :/
Here are the screenshots of email comunication

If no then you still have a fault here, although this is just based on my own analysis of what is happening and the possible cause of your problem.
