Not impressed !!!!!!

On the 25th of October we recieved our Yoco card reader.. Ever since they have been debiting us twice. And the agreement is once a week.. when I called yoco they referred me to Retail capital.. when I called retail capital they told me that we have two devices that's why they debiting twice.. I called Yoco to confirm that I only have one device.. I've spoken to Tanya Ross from retail capital about this and she told me it's sorted.. but still they are debiting me twice.. and the bank charges is accumulating... the bank account is already on -R700 just because of Retail Capital...
