Ok, i sold something on ebay, the person paid me via paypal to my sister's bank account and told me to ship it via regular mail instead of priority (which i usu. use). So i go to the post office and the clerk tells me that i can't put delivery confirmation on regular mail only priority. She recommends i get Certificate of Mailing(it costs 90cents compared to 55 cents for delivery confirmation) so i'm like ok fine. I ship the thing and the person claims they never got it. I was checking her rating on ebay and she has 3 positive and 1 negative and i have a rating of 66. I"m sure she's trying to swindle me out of this thing, but apparently paypal says i have no case because i have no way of tracking whether or not they received the item. Even though i have the certificate of mailing and the email telling me to ship regular mail. What should i do? Will paypal take money out of the bank account w/o my permission? I want to close that bank account so they can't. Is that possible?
