I deposited cash in a Capitec atm and the machine cancelled my transaction and then it was out of service. I waited for the money to be returned back but it didnt. It was an atm without a branch. l called their 24hr hot line. I explained my situation and they told me they will do investigation and call me back in after 24 hours. They did not call me back. After l week l called them and they sent me from pillar to post without any help. They said they will me back again they never called. I called them again and they told me case has been closed because they couldnt trace the money. They told me since l am not sastisfied l must send email to the atm department. Sent email and till today they havent responded. They have not sent a message or email to inform me of their feedback. I am very dissapointed because l lost my money and no apology and no refund was sent because of their old machines that they havent upgraded thats why it chowed my money.
