Terrible service

<p>I am a client of vodacom and has numerous contracts with them. Each of these contract have never been used for phonecalls. Here is one of my contract numbers is ********** , ********** , ********** and ********** and the others i dont even know cause everytime i upgrade i dont take a sim with it as i use my pre paid number to use. They can see my amount due every month is around R2000 and something. The end of June 2017 they want to deduct an amount of R12 000 and something which i dis not have in my account and then it was send back as no funds and i was charged by my bank for the fee of R3000. I phoned them immediatly and they said they will contact me. How is it possible that an account can go from R2000 to 12 000?? I dont even use some of the telephone numbers as i use my pre-paid sim card. The others are not being used for phonecalls and has a limit on them only for data. Vodacom never came back to me but simply send messages that my accounts will be suspended. This im not leaving here. They must explain to me what is going on because i know i dont use the sim and the others os just giving a data that they can use then we can buy airtime further. This i find quite disturbing and embassing. Im going to take this further even if it is the press. I want this fault of them to be corrected. Im really fed up with vodacom.</p>
