ATM took my money

ATM took my money I went to a capitec branch at Thabong Shopping Centre in Sebokeng on Sunday 2nd December at 17:05 to do a deposit. After the machine took the money it counted and before it gave me the option to put the account number it wrote transaction cancelled and never returned the money. I then called the capitec call centre immediately and i spoke to a consultant that asked me a lot of question and ended up telling me that they will investigate and come back to me. I then went to the branch in Monday and the consultant that was assiting me then called their head office and was on the phone for a long time before telling me that capitec is experiencing a backlog and I have to wait 7 days I then went back today and was told the same thing. Meanwhile I want my money to be tetirned to me I feel that capitec is not putting its clients concerns first. I'm so annoyed with the service I'm getting and I need an explanation
