Florie Alandt, why go under all the trouble to get a partial refund? Call your credit card company tell them you have been scammed online by this fake company and let them do the investigation. Mean while, they will freeze any additional charge coming in from that "teethwhite" company and your credit card company should be able to give you an initial refund. Addtional precaution: make sure to keep the return tracking number for the package, so that you can prove to credit card company that you have returned the item but not getting refund back.

I'm sure if there are this many complaints on this here, them credit card company has probably put "teethwhite" company on their scam radar.

Anyway, I have this happen to me once before, I called the company and they say they don't even know me, so I can my credit card company told them I have been scammed online.

GoodLuck
