Vodacom took money from my account without my authorization

Vodacom has just debited R 1599 from my account which I did not authorize. Someone from their call centre called me more than a week ago to ask if I took out an IPhone 11 and I said no. So now a see there’s money taken from my account. I called this morning and I’m told it’s probably ***** and I must go open a case, provide 3 signatures!!! Why must I be inconvenienced.... I want my money back now. I’m a working and I don’t have time to fix Vodacom’s mistakes... someone needs to tell me a better solution than running around to police stations, being sent to ***** departments (and my call was dropped by the Vodacom ***** department in less than 1 minute by the way)..I need a solution that does not involve me being inconvenienced...
