My seller account was deactivated because I had an old listing of a 3G mobile phone which was fine when I listed it but later breached amazon rules when amazon introduced a rule that it no longer allowed listing of 3G mobiles. I then removed the listing and my amazon health page showed this and showed my Account Health as unaffected. However, my seller account is still deactivated and I can't see what else I need to do to reactivate it.
