I dropped off a prepaid package w/[number removed] 8073 2929 37) at the West Portal Post office in San Francisco on the prepaid package counter and had paid beyond the required amount for the weight and dimensions. One week later, the USPS website still hadn't registered that it had been dropped off to the post office. I went back to West Portal post office and was told the same thing. They gave me a phone number to an automated response system with no luck on my end. When pressed to provide an explanation for the lost parcel, the post office attendant acknowledged that they sometimes get too busy and fail to scan all of the dropped off items. Now, one week later my buyer wants a refund for the missing parcel and I have no idea where it is. Nice going USPS. So from now on, whenever I drop off packages to USPS, I get a receipt for every prepaid item.


I went into the West Portal Post Office, the line was long, this is COVID-time, I am in a high risk-group, and I wanted to drop off the pre-paid labeled package without standing in the line to get a receipt. However, I was aggressively questioned by an employee, stating "you do not have enough postage, I know, that looks over 13 ounces"--I told her that my prepaid label was up to 1 pound, and she said I was wrong--13 ounces was the limit, and she threatened to send my package back to me. I left the package, because if it was one ounce over, USPS is supposed to deliver the package per Mercari policies, and charge me for any excess. However, this package was routed back to me, noting postage due of $2.35, which invalidated my prepaid label. And to complicate things further, Mercari still thinks the package was delivered to the buyer! This has caused a bit of a mess, and of course a delay, and I am not happy that I had to buy additional postage to send this package. I will be in contact with the supervisor of this local post office; however, the phone just rings and rings. Oh my. Lesson learned--do not go to this local post office!
