***** on my account

All the money in my bank account was taken by someone. The ***** bought airtime and cellphone recharges worth over 8000. I did not receive notification of unusual activity on my account from the bank. Nor did I get the usual sms notification of transactions on my phone. I realised that my money was ****** when I tried to make a purchase and it declined. What happened to the security of our money in banks. To make matters worse I still have not been assisted by the bank despite going to different Capitec branches. I keep being told that the matter is being investigated. How long! It's January and my kids must go to school. Surely this justifies moving banks. I am very displeased.
