Can anyone tell me how I can apply for a refund for "guaranteed delivery" that was a day late? I used USPS Express Mail and instead of getting there overnight, it took 2 days and my customer was furious.
I have been to 2 post offices, and one told me to bring the receipt in and they will take care of it. When I brought the receipt and tracking number in, another clerk told me that I have to do it through my software. Any know what I have to do?
