Avoid Viatek like the plague!!!!

I was contacted in 2014 with an offer from Viatek for printer cartridges and cleaning agents. <br> I ordered both printer cartridges and a cleaning agent and it arrived within a week or so.<br> <br> THEN the agents started harassing me for the next order.<br> <br> I made it clear that the cartridges were still adequate and the cleaning agent was not up to our expectations.<br> <br> These guys then kept on harassing me for payment for goods that I did not order. <br> <br> They will call you 10+ times a day.<br> <br> This is STILL going on.<br> <br> HOW do I make them go away?!?<br> <br> AVOID like the plague!!!
