I'm not sure if this post is in the right place or not, but I could use some advice on something. I purchased a DAP on the Trading section of the board from another user (depending on what I'm advised to do I'll be happy to give the user name). The DAP was paid for last Friday, as the seller said he was in a rush to ship. I assumed they would ship Saturday, but this wasn't the case and they said they'd ship on Monday. On this past Monday I asked if they might have any tracking information for me. The seller told me that they didn't have it, but if he found it they would take a picture of it and send it to me. The next day, after asking another question (and feeling that something was off), I was told that they wouldn't be finding the shipping info, and that the DAP (a Hiby R3) was actually shipped on a day USPS was closed (this past Sunday). The seller, this entire time, has acted angry any time I've had a question or concern about this. They finally did tell me that the item was shipped by USPS, after dodging the question numerous times. I have to admit that, because the seller acted angry because of the PayPal fees they'd have to pay I paid them thru the "friends and family" part of PayPal (I know, I know). Now they haven't responded to my messages or texts in two days, and supposedly they're on vacation. I haven't received anything, and thru USPS Informed Delivery I have no packages coming to my address still. I'm assuming I've been scammed here. What action can and should I take?
