No Reply from support on tickets sent in 5 days

First the good: Great machine, got the Khumo Print. Very smooth and user friendly, delivery was quick and the machine came pre-configured and ready to go. Initially it wouldn't accept any taps or inserts, only swiping, but after rebooting the unit, it was working. If you manage to exit the Yoco settings and enter the android settings after awhile you are unable to get the back and home button bar back and you have to reboot the machine to get to the POS screen again. Thursday 9 March 2023 I submitted a ticket on their website. #***2, today 13 Mar 2023 still no reply. Friday 10 March I sent an email #***5, still no reply. On Thursday / Friday I tried the chat service, the whatsapp line is just a self-help useless story. After about 30 mins of waiting I got through to someone on the website chat, they asked me to send a video of my issue, when I rep**** I was disconnected for some reason. Today I found hidden a support number at the bottom of a status email and managed to get through to someone and cancelled. If I got a reply back the same day from Yoco support I might have kept the machine.
