Snapon smile (Fake) I have not seen any other names Ordered Teeth Whitening "Snapon Smile" and received a Fake

I was on Facebook Market Place, and an ad came up for a whitening product. I saw that it was not that exspensive. So, I took a chance and learned to regret it upon receipt. I received the item and when I opened the package there were 4 things in there. 2 of the things in there, I could not identify. If there is an option to add photos I will. The other 2 things were obviously what you put on your teeth. 

I will say that once I actually looked it up, there was a video that showed how it is supposed to work. That was when I realized it was a fake for sure. The video clearly states that there is a process for this "Snapon" process. The product was not listed as "Snapon". So, I'm sorry if this still happens to you. I looked up whatever the name actually was and did not find anything. So, I figured that it was a small business. I should not have been so Naive for $40. I mean it's not a lot of money, but it sure does add up if this is happening to multiple people. 

Here is the thing, you can't get your money back for this. If you did it using paypal at checkout, then it was an authorized purchase. If you used your bank card at checkout, then it was an authorized purchase. Facebook does not protect you unless it was specifically a "Facebook Marketplace" purchase. If it was an ad, that can be literally anyone. You can start an add right now to sell something. The only way you get your money back is if you let your bank/paypal/Applepay/Googlyplay(or pay not really sure because I have an iPhone) know that it was a minor that made the purchase. This would be considered an "unauthorized purchase". 

The return & refund policy card only has an email on it. I refuse to actually email it, because I know that people can send viruses through email. So, the responding email could very well take over my computer and or get my information that is stored. I know this was long. The point is DO NOT EVER PURCHASE ANYTHING USING A FACEBOOK AD OR AN INSTAGRAM AD OR A TWITTER AD!!! Only Purchase from places that give you guaranteed purchase protection. 

***NOTE: THIS PERSON MAY HAVE ALREADY STOPPED SELLING WHAT HE SOLD TO ME. HOWEVER, I HAVE SEEN THAT HE/SHE HAS SOLD OTHER THINGS WITH THE SAME EMAIL. PLEASE BE CAREFUL.***
