Re: Uzzu.tv–Lots of reviews complain about fake refund promises, and recommend using a single-use credit card. They claim to be in “the States” and you can visit at 90 N Gould St, Sheridan WY (no zip given). Google maps shows that address to be associated with “Swiftify” of 30 N Gould Street, which according to the Sheridan newspaper is the location of a well-known “registered agent” of hundreds, maybe thousands, of fly-by-night companies. I.e., ain’t no company there, just an “I know nothing” bozo who files papers. Being monitored by the Wyoming A.G. office.
The Uzzu app was removed from Firestick and elsewhere, and they offer instructions for sideloading onto Firestick, Apple products, phones, smart tvs, Roku, etc., using a login code they give you.
No phone number, no domain name revealed in their email, no physical contact info. Yep, sounds legit to me.
