When issuing my shipping label, I noticed that the buyer address seemed incorrect. After some research using Google Maps, the address I have on
file "7830 NW 71ST ST
MIAMI FL 33195-2339 SERV0158414 MIAMI, FL 33166-234" does NOT match any
University (Universidad in Spanish). The buyer address says that the packet
should go to "UNIVERSIDAD SAN GREGORIO DE PORTOVIEJO" located at this address, but there this nothing located at this address with this name.
According to Google Maps, only some warehouse are located at the address provided by the buyer. Buyer never replied to my emails.

Because this was a pricey item this buyer was probably going to start an "item non received" claim, followed by a A to Z claim against me. That
way he can keep the item and get his money back.

Contacted Amazon customer services and they agreed to cancel the transaction.

Seller beware!!
