Viatek is a **** that won't go away!!!!

Absolutely the most horrible **** to get into. Viatek, who i would keep reporting on all social media platforms until they stop harassing me. I had accepted a 3 box of cartridges contract and had paid of it then did not renew my contract and cancel it, with them accepting my cancellation. Then soon after getting a call to tell me that i have not use my 3 boxes and need to pay in for the next one because i havent gotten anything according to the system. after saying wat feels like 1000 times i really do not need more ink, they keep on calling me. tell them to sue me for not paying and they still call tell them to cancel and pay cancelation fee they still call send all cartridges back that they send and tell them you dnt want it, they send it back and call for payment. Please can someone tell me how the HELL do i get out of the RED Hot circle of Viatek?
