Poor poor services

I have bought a yoco machine the past year; used a different banking details now I want to change it; the yoco platform doesn’t allow me to, I contacted the yoco team but I have been tossed from pillar to post it seems they can’t assist they say I’m not the owner even though I have a profile of the company and the machine linked to their platform; I was asked to send FICA documents for verification but there is no joy; I’m currently on their online platform; agents are sending me to different agents passing the buck; I want to use this machine since most of my clients prefer card less and cashless platform for convenient but Yoco is not convenient for me, while I’m using their unreliable platform where it’s not user friendly. I’m frustrated
