Vodacom data... never again...

I am horrified by the way Vodacom is exploiting me… Though they finally admitted their mistake, they have been dragging their feet for months i.t.o. closing out my issue. In summary… I had a 3G account with 3 SIMs registered for it. Though the contractual 24 month period lapsed, I was never notified or encouraged to upgrade…anyway… separate issue… On requesting a cancellation of the above mentioned contract, I was convinced to switch to a new 40Mb contract, still with 3 Sims and a new WiFi router. It was promised to be a seamless switch with no additional costs from my side whatsoever and that the switch would be immediate. Well… it turned out that none of the above was ever possible as they eventually admitted… so I was taken for a long, expensive ride… they squeezed a lot of money out of me in the process…which I still hope to recover! The WiFi router was delivered in good time and my 3 Sims continued to work “seamlessly” as was promised… guessed what happened… Upgrade never done due to technical **** on their side… My data usage ran over the “old” 3 Gig limit and I were not notified… this overrun was in excess of R1200!! So I got charged for that… the 3 Sims stopped working and I have not used any data ever since… The ********** number is a joke as I have been sent from pillar to post and have been aimlessly transferred or my call ended numerous times. The excuse seems to be that they can process the cancellation only when the router is returned… They have been unable to process this since the end of June and my suggestion of simply dropping it off at a Vodacom shop seems too much to ask from them… They still charge me ona monthly basis as if the contract was still valid and active… What a disgrace…
