******* Charges on my account

I've been a Vodacom contract customer for 25 years. Vodacom seem to have climbed into bed with ****sters *******ly deducting fees against your account to which you never agreed. I'm down R2700 so far, with the prospect of having sit in a callcenter queue to convince an agent of something that has nothing to do with me. They are enabling theft on a massive scale and profiting from the proceeds. Why not give me the option to NEVER accept any 3rd party charges against my account? That would give me, the customer, control of my own account?
