Error Ban 3rd account

[jdr2024b]

Hello,

Your system has a problem, it automatically banned my 3rd account, your system detected a 4th account even though I only created 3 accounts no more.
My 3rd account was disconnected, then I reconnect normally, I receive the message you are connected.
I reconnect with Force Log
I receive the ban message. I see that the name of the so-called 4th account is identical to the name of the 3rd account. Your system has created a 4th ghost account. The 3rd account I created with the Referral System of the first account, I read that there is a problem with the Referral System.

How do I contact customer service, I don't have the link to contact them?
