Ebay Problem/ reading a postal receipt?

Question

Someone brought a textbook from me on Half.com a subsidiary of ebay. When the book didn't arrive on the latest expected date she sent me an e-mail. I told her I mailed the package the day after she ordered it and showed her the address I mailed it too. That was 3 weeks ago. Now she's asking for her money back. I found my receipt. Below my zip code it has a 10 digit number along with a dash then a 4 digit number. Is that the track and confirm number. I put that in the track and confirm on USPS.gov but nothing came up. There's also a bill number. How do I find where this package is? Also I'm having a strange feeling about this person like why did she wait 3 weeks between e-mails. any suggestions?

Answer 1

its not your problem, you sent it! she should contact the courier directly with the 10 digit number

Answer 2

Take the receipt to the post office and ask them to track it.
