Checked with my colleagues and this seller is not part of our authorized sellers on Aliexpress. We don't sell them our products directly, neither should any of our main distributors.
So unfortunately, we have no power over this seller. We also don't know if they even had any UP2 in stock or if they just got some small supply from main Chinese market and then run out of it.
Now you can either try to ask them for refund or dispute it directly with Aliexpress.
Thank you for the info.
In fact, the information provided by the seller was rather shabby. They also sent the product on the last day of the processing time.
