Long story short I was sold a used bag described as BNWT. After several days of haggling with the seller, she finally agreed to a return ONLY after I opened a Paypal claim and it froze her account. I mailed the back back to her ASAP, via USPS Priority Mail and of course did signature confirmation to prove she received it for my records. I also sent her the tracking into as soon as I have it. When she finally agreed to the return, she also asked me to cancel the dispute. Because I caught her in a few lies, I told her I would, as soon as my money was returned. Anyway, USPS has attempted t deliver the bag to her and now it's sitting at her post office for a few days. I have written her to advise it's there and heard nothing. What should I do if she refuses to sign or pick it up?
