Money back gaurentee yet no money...No service... No device

I have returned my device nearly a month ago after having it for a weekend only.

I was told they would refund the cash into my account. A week went by i heard nothing, i called them they said they will escalate to thee department. Another week gone and i havent heard anything. I called again i was told they didnt log it to the correct department. I asked to speak to manager conveniently the manager is in a meeting. The oerson then on the phone assured me that he will sort it it out. A other week gone by and. I heard nothing again. I called. Yoco again i asked for a manager again and was told that there is not one available as frustrating as things are waiting for my refund not hearing anything from there side they informes me the refund will be done 7 till 10 working days which is rediculous.

I only returend the card machine as we are starting uo thinga are slow but we growing steadily. When we have a bigger request for swipe facility i will reather go with ikhoka or any other brand besides yoco
