Bad service and false advertising

I am an iKhokha card machine user for the past 2 and a half months. Ever since I got my machine it hasn't accepted Capitec bank cards. The transaction always declined with an error message. I have made numerous calls to the service centre for assistance. Every time I was given a different excuse. It started the assistant refreshing and clearing the cache on my machine numerous times. To being told that iKhokha did have an issue on all their machines with Capitec previously but now it's been sorted. Then it went back to clearing the cache on my machine. Then it went to they can't figure out why only my machine has an issue and I was asked to send through pictures of the error message. Today the 12.07.2025 I was advised that I need to ask all my customers to go to their bank and sort it out with the bank as it's a fault with their cards. This makes no sense as the exact same card will swipe on a different traders iKhokha machine but not mine, so how can it be an issue with their cards. The agent went on to tell me that there is nothing wrong on their side which I feel is lies because why was I given the run around. This is truly false advertising as I was never informed that there is an issue with Capitec cards and iKhokha. I refuse to accept this experience and explanations as if I was informed about the issue with Capitec cards I would have of never agreed to purchasing an iKhokha machine. Or why was this not mentioned to me within my 30 day refund period. I am very unhappy with this machine and the service of every single person that I dealt with at iKhokha
