*****ulent activity on my account

On Friday morning I noticed a debit of R590 on my account, it went off my secondary account which is never used for outgoing transactions. I tried to query on the app and the only information was a number*** which I called and it was a capitec number but it went unanswered. I reloaded airtime at business hours and still got no answer so I went the bank. The man said it looked like a *****ulent transaction but wouldn't be able to reverse it. I asked what company this was and they gave no answers, they told me to Google the number. I asked what should I do now and they said "unfortunately there's nothing we can do for you"..i have screenshots by the way. Then another transaction for my Mtn internet went off but Mtn kept saying I had not put funds for the wifi. I called the bank to query and they said it was too soon to tell, wait 24 hours and call again. I did as advised, called back and was told it would be escalated. I keep calling to find out about that too but the only consistency from capitec is rude customer care agents who send me from pillar to post.
