I filed my dispute last night. They responded quickly and said it was picked up yesterday. I was told Monday it would be picked up Monday. So may be I'll have my stuff this week.
ETA- So since I still did not see a USPS scan I called to ask what is procedure? USPS stated if they picked up on 12/31, there would be a scan on it (of course when she tracked she only saw electronic info rec'd). She said even if there was a chance they did not scan at p/u which is rare, there would be a scan by now that they had it. I added this info to my pp dispute, and asked to just be refunded, do not mail it today.
I would be fine if they were just honest with the shipping, but they are not. There is just no reason to print a label 12 days ago and not send. There was ample time to get it picked or bring to post office before, around, after the holidays.
