Yoco disaster

I have been using Yoco for a few years now, very happy... until last week. What a horrific nightmare - They just stopped payouts of my hard earned money, without warning & due chance to rectify the technical issue they all of a sudden have. For the past week I have been in contact numerous times with support and activation, jumping through their hoops and getting nowhere. I need to change my sign up details and banking details, but nowhere do I have an option or procedure to follow. The business portal is useless to change such. My money is still not paid out. To be honest, I'm not sure I will ever get my money. Needless to say, I will terminate using the Yoco device to accept card payments. It is like working long hours & then just hearing that, oh, sorry, you won't be paid, since we cannot sort out our technical issues... The device is good, but maybe they just have no clue how to support or manage these types of problems. So frustrated and disappointed!!
