No safety with Capitec Bank

waking up to an sms about a purchase that I made 5 days ago. this morning at 03:26am I received an sms that reflects and mirrors a purchase I made at clicks on Monday 7 Sep 2020. This transaction went off again today 11 Sep 2020. call centre does not answer, its not even a toll free number so you are expected to have hundreds of rands in airtime waiting for your call to be answered, oh and how do I purchase myself airtime if this bank double debts my account every time I make a purchase. level of service for their clients are terrible.
