Still waiting in vain

I went to Vodacom to complain about the contract which activated without my knowledge, they investigated sand dismissed the guy who ********** activated the contract on my behalf, shocking enough they are still deducting money from my account, they requested an affidavit I submitted it in February up until now they haven't resolved my query. Can someone assist me as this is truly inconveniencing me . I know no ones bothers to call customers when you need feedback they can only call when you are on arrears
