Started on a high and now going down the drain

Have been with yoco around 2-3 years now, at first service was amazing everything was convenient and problems were sorted out quickly. Nowadays the machines are giving me so much hassles I’ve had a couple of replacements after constantly contacting them. My clients come from all over and its so embarrassing when the machine just decides to give in. Why does it want to update when I am trying to make a transaction? And it takes ages to load. The service has gone down, they take forever to respond and end chats when you not even done talking. They tell you to do the same thing 100 times after you have already told them its not working! Get better machines and pay attention to your staff thats going backwards please otherwise it’s just really not worth it there are other options.
