Security compromised by my trusted bank

I purchased an airtime today using my capitec app but to my surprise my account was Deducted three times leaving me with 2 unwanted airtime. I called vodacom for refund unfortunately vodacom couldn't assist because is prepaid transactions made through the bank ,Vodacom agent Keitumetse transferred me to Capitec agent Petra who explained thoroughly how the bank can't assist because the transactions is prepaid and happened on different time intervals,enforcing that I,the client pressed three times ,which i still remember in my full sense that i confirmed once.Now as a customer I am caught in the middle with my money gone and no help available. My question is am I safe in this bank because my money is out and they don't know what happened.

My security is compromised and I am scared because it's my main account. But it just that I didn't listen when people were warning me that money goes missing at Capitec and you won't get a refund.
