Unfair billing

After writing a review on hellopeter vodacom called me, I thought they going to help me but only to leave me confused and angry more..first they tell me that they gonna refund me cause on their system it shows they are billing me two phones separately.. Meaning R480 + R480 instead of R480 only but to my surprise they call again to say for them to bill me so much money is because I insured the phones which I don't know about that and when I was applying I specifically said no insurance .. For them to say I am paying insurance which they did not have my consent about that, after telling me that they have to pay me back for the wrong billing left my emotions all over.. If you want to be stress free avoid Vodacom
