lack of concern for customers

On the 26th of February I withdraw R350 and got R170 short and from an Nedbank ATM . It’s the 2nd time it’s happened to me at the same ATM that I received the wrong amount. I logged a dispute with Capitec and was told it would take 30 days to investigate. After the 30days I called in on the 26th of March and was told this is still under investigation it would 2 to 3 working the agent will send an sms. After being on the call with Capitec I get an sms saying, “Good day As per findings it shows that transactions was successful money did come out. therefore no refund is due. The transaction was successful but the whole amount did not come from the ATM! Why wouldn’t the agent tell me this on the call why do get sent an sms after I have called, something does not seem right. I called in yesterday once again and spoke to Nokuthula, who was unable to help therefore I asked to speak to a manger Fahiem who also couldn’t help me and said I need to speak the Capitec complaints department. He transferred me. I held on for an hour no one answers that number for complaints. I called that number again this morning still no answer (that number does not work)!!!!. I would like to get this matter resolved please. This has really been a tedious process. I can get Lawyers involved and deal with this the legal way I really don’t want this to get ugly. I will take this matter further. The lack of concern from Captiec Bank is rather ridiculous and pathetic!
