Yoco disgusting service and business ethics

I purchased the machine did 1 transaction for R150 which was never paid into my account. I spoke to mandisi who did not even try to resolve the issue but once I asked how do I get a refund he said he canceled my account as per MY REQUEST. This company has no morals and should not be allowed to handle people's money. Mandisi advised me they will be collecting the machine I will not be returning it as I have now read many reviews that state once the machine is returned THE CUSTOMER NEVER GETS A REFUND. Horrible service you can never get a call back or even get through to they call centre's. Worst mistake of my life.
