Ebay Purchase: Item not received reported, then seller changed the tracking # to new one
I purchased a large Bose speaker on Ebay. It showed shipped from China immediately and started showing departed port after on August 3rd and in route. Then, stopped showing progress but had an August 15th delivery expected date. No delivery by August 16th, so contacted Ebay for help, next day seller changed the tracking # to new one and shows it was delivered on August 2nd in a mail box and the shipment now shows started from CA and not China. No delivery address and obviously no delivery of the item.
How can the scammers make up a tracking # and change the tracking numbers without a trace ? E-bay AI service says, no help. Trying to reach E-bay service agents with no luck. Anyone experienced such a day light ripoff on Ebay? Any suggestions to resolve this?
