From a nice company to do business with to a bad one in the wink of an eye

I have started having huge problems with Yoco systems, instructions, reports and communications recently And this started before their system crashed on the 29th. They dont answer their phone in a reasonable time, and emails and the chatbots get directed to FAQ which dont provide answers, which is why I have tried to communicate by other means in the first place. What a pity - used to be so good.
