Vodacom

I have a contract with Vodacom for the last 10 years or so and never had problems but from last year when i went to do my upgrade they said ill be only paying this amount for 4months and then all of a sudden after this lock down they want to tell me i owe money to them and i started doing my investigation at springs branch where i did my upgrade and they told me its not there problem I must go to Lakeside Mall in benoni and now when I phone head Office to assist my they also want to throw there hands up like I must just pay them im tired of because after doing investigation they owe me money but Vodacom can just decide from theire side they ***** money from as customer and throw theire hands up like we must just pay and thats it so they can just take my money like they want and add stuff on the account like they want and when you start qeustioning them they make like its nothing. I mean in springs branch they tell me not theire problem and in lakeside mall branch the lady can show me and tell me on black and white that Vodacom has been taking money for free and charging me like they want so stay away from Vodacom as im going to cancel all my contracts and my companys from Vodacom.
