I am unable to access my seller central ads account for more than three days. Despite raising chat on Amazon, they have redirected to advertising team and told you will receive mail. But still I have not received any response till date to get this issue fixed. When I go to Advertising > campaign manager , it shows page isn't working - redirected too many times, I cleared all cache and cookies, changed internet connection, browser everything, still no hope.

If I go to Ad sales drop down from dashboard, I can access ads account from which it prompts to select our account and country, Once we do it, it loops to same selection. Nothing can be done to access campaign manager.
