I cant get into my Amazon seller account!

I went to log into my account once it took my credentials it took me to a page saying my account was not registered. It had a button I could push to register so I did. It then rerouted me to the sign up page so I clicked “Sign up” since I cant Log in. Once on the Sign up page it wont let me sign up saying I already have an account with this email. Need some advise since I cant get Amazon on the phone.
