Yoco bad service

Good day Wonderful people

I bought a brand new yoco pro machine was so happy to register. It took me a week before I could finally use it no problem I was so happy to do 4 transactions. However my 5th transaction and ever since didn't go through because the clever people at YOCO decided to remove my machine from my profile and assign it to another business. Been trying to get this sorted but everytime they tell me we will phone you in 5 minutes but I am still waiting. Nothing happened and I am losing business and customers because of their inability. DO NOT JOIN RUN AND RUN FAAAAAAAAAAAR AWAY FROM YOCO
