Shame on you Ikhokha

My Ikhokha card machine is in immaculate condition. I do markets for a living therefore haven't had much use for my machine of late (due to Covid). I'm doing my first market for 2021 today and my card machine won't work due to "System error! Invalid keys!" The sales lady referred me to technical support who tell me that my machine is older than a year, therefore out of warranty. I'm told that the machine can't be fixed and I can throw it away. I'm also told that the only reason for it to stop working is because It was dropped. It was not dropped. If your card machines have a short lifespan, don't you think you should look at this or at least mention this to your clients. I paid full price for my machine, not R499 on special! I have referred other vendors due to good service, until now. I'm truly disappointed!
