The seller claims to have shipped two packages from China, once on 10/17/2013, and again on 12/24/2013.
Neither package ever arrived. Meanwhile, dozens of other parcels arrived at my residence in Phoenix during the same period, from multiple carriers, without any issues whatsoever.
The probability of two independent shipments going missing due to "shipper error" is remote. What's more, the seller's refusal to refund my $12.99 leads me to believe this to be a case of fraud.
I have escalated this incident to the following authorities:
(1) my bank
(2) the Paypal fraud & claims department
(3) the Google Trusted Stores Program
