Stay away from thieving Vodacom

So Vodacom has been *****ing money from me for the last 18 months. Been trying for months and months to try and resolve it and I am being sent from pillar to post. Trying to not get bad credit and not pay for a device I don't have, I pay them every single month for mistake that is not mine! I then get a call from Randall to say it will be sorted but that the double charge for ONE device will be credit and paid to my bank account. Great news right? Not a f-k!. Now I get a call from another agent telling me that I will be credited to my Vodacom account. I again told him about Randall and what he told me and that it will be returned to my bank account. I then said to him, ok, no problem then I just won't pay you for the next few months... I ask him to confirm the amount that will be credited to my Vodacom account and it is one month! One month of R128.99 and not for 18 months as originally told to me by Randall. Kagiso will now go an investigate further and call me back. I am so livid! What kind of ****ery is this! I mean... How are you making this my problem Vodacom, how?
