My daughter baught item from a Disney seller on FB and used PayPal. She only received one portion of her items. When my daughter disputed, the seller gave PayPal a tracking number for the first purchase and said she had mailed all items in that shipment. My daughter offered to share the FB private messages which includes admission from seller that what she told PayPal was false, PayPal said they could not use those messages. Now they've sided with the seller after telling my daughter that this would be resolved as a seller could not use one tracking number for multiple different orders. This company's customer service is all over the place as well, you get a different answer every time you talk to someone!
This is totally ridiculous. I know that there are reputable sellers out there, but please stay away from these scammers that make their pages private. You can't review them and can't verify if they're a legitimate business.
