Lack of competence.

I am so frustrated with Vodacom, I payed my account at Clear water Vodacom, then same day vodacom debited my account and I had not authorized that. The lady I spoke to suggested I go pay at the store and I did that. Now I am struggling with getting help with reversing the money they deducted from my account. No one seems to know how to assist me. It’s a lot of money and I need it,
