Doing deal with OP already sent half the payment. Will update once phone arrives. I have previously done business with this guy before and hope it turns out as good as the last time
First of all, you send already half of payment to an unknown seller without using Escrow?! Not a good move.
Second (and weird/shady) you state that you have done deals with Op before but you are both newbies here, so where and how you done these deals already?
For me even if you post that everything goes smooth and the Op is legit, i will highly doubt about it.
Op has not being seen (that's much of a seller...) and you send him
BTC and communicate with him via PM's...
Btw, can you post this TXid of your "payment"?
