Don’t take a contract with Vodacom

I am so disgusted with Vodacom I took out a contract in February and did not opt for insurance or a top up. I made it very clear because the consultant advised me if I don’t use the SIM card I would not be able to claim so I decided to take out insurance else where. Two months in a row Vodacom has taken out over 600 off my account something I did not sign to and agree to. When I called they told me it is for insurance plus the account is for someone else what the hell?????? My bank account is gone into overdraft because of their incompetence I am ****ed off and want this matter sorted out. I am going to reserve these payments until this is sorted and then cancel my contract. I should of never taken out a contract with Vodacom. I have never experienced such with other service providers. And then I’m told this was just activated by voda phone imagine I cannot believe this.
