Amazon Account Deactivated

Hey guys, I’m pretty new to amazon FBA, but recently my account got deactivated because I apparently have 2 accounts on Amazon seller. I will admit that my son made one a long time ago and “deactivated” it. I admit this is definitely my fault but all the letters I sent to amazon and they still won’t open my account. I’ve invested a bunch of money into this and really don’t want to lose it, any ways you guys could help me? I get that this is my mistake I just dont know how to fix it, I’ve sent numerous emails and submissions to amazon but still nothing.
