Hi. In an effort to change my email address, I deleted my Amazon Seller account (United States marketplace) as recommended by an Amazon representative. I have since discovered you may only have one account. I did not know this before trying multiple times to set up new accounts - all rejected. Today, I logged back in to my original Amazon Seller account. Adding the United States marketplace was not an option so I chose the United Kingdom marketplace. How do I reactivate the United States marketplace and remove the United Kingdom marketplace? Thank you, in advance, for any and all assistance.
