Inactive card machine / unprofessionalism in terms of communication

I bought a card machine with Capitec with the understanding that it will reduce more cash transaction. Capitec bank has employed people and gave them responsibility and powers to assist public and some of them . abuse those powers . There is this individual who has failed to work on my case after closing the machine without communicating the reason for the decision taken. I went to the branch in hartswater and still could not find the solution to the problem. I do not have a reference number because they have not responded to my email .
