Total lack of help and understanding!

The same day my card machine arrived (20.02.2020) I tried a practice swipe - I mistakenly did a R40 000 transaction instead of R400. I immediately (within seconds!!!) contacted Yoco support (Keenan) who was very helpful and escalated my ticket. I then contact support again (05.02.2020 - Azraah) where I was told it was still being dealt with. I then contacted support again and again was told that my ticket was still open. Today I contact support (Tlangi) who was very helpul but then advised that Yoco was not going to help me. I have now paid a fee of R1357.00 from a mistake that Yoco is unwilling to help me with. I am currently, like many people in financial crisis. And I am utterly disappointed with Yoco in handling of this issue!
