Business Name or Personal Name under Sole Proprietor Entity

I'm in the process of trying to reactivate my USA account and struggling to do so without any help from Amazon.

Only thing I can think of is having my Business Name as my 'Legal business Name' despite being registered as a Sole Trader/Proprietor

I've noticed with Amazon Canada etc, they say to put your Personal name as the Business name if you're not registered as a business.

Cna someone help please because all of my accounts have been deactivated because of this.

My UK Seller account was working fine for a few months until my USA account was recently deactivated, despite having my Personal Name as my legal Business Name on UK account
