Shocking customer service

I bought a Wave TV Box, from a Gino, who was selling them at the Italian Club in 2019. Had nothing but problems, I was promised an invoice by email, still waiting. My subscription expired last year, and unable to renew it. I have tried to no avail to contact Gino, he has changed numbers, and I get told theses stories how sorry they are, and they will sort it out...ABSOLUTELY SHOCKING SERVICE. Its a wonder that these kind of businesses stay in business. Tried calling both cell numbers n the website, straight to voice mail.
