Replying to Advice for not getting merchandise.

hello ns I know there are threads talking about selling/ buying at your own risk. but I need your help/ advice.

I recently bought a Canon t2i from a ns'er, with the lenses, and some memory cards. I have his number and texted him a lot about the deal and just friendly stuff. I called him and
emailed him various times. he agreed with the deal and said he would ship. I kept on asking for the tracking number and he would not answer, even though he said he was looking for it. he said he put one day shipping on it and shipped it last Sunday, and it has not arrived yet.

I payed with PayPal and I have record of the transaction.

anyone have advice?
