Please, telling them you have chosen NOT to be an IBO, they will refund their share of your application fee. They’re really good about that.
Their main headquarters is:
7575 East Fulton
Ada, Michigan USA 40301
But I’m sure if you look over your information, you can find a “local” address for the Corporation. Just make sure it says “Amway”.
You possibly paid more than Amway’s fee to some sort of Motivational Group – the group your sponsor is in. They *might* refund your money – but will probably pressure you to stay in. Just tell them you’ve sent your letter of resignation to the Amway Corporation; and they will go away.
