Worst network with *********** staff

I have had the worst experience with this network. Firstly I get subscribed to online pages which use up my airtime immediately after it has been loaded. Last month I phoned the call centre and I was assured that the subscriptions had been cancelled and I won't experience the same problem in future. This agent further advised me to timeously dial *117# to cancel any unwanted subscriptions which I did without fail. This morning I wake up to 88c left as my airtime. I phone Vodacom again. Speak to an agent by the name of Nontobeko or Ntobeko, I can't recall. She tells me that the subscriptions were not cancelled, as said by the previous agent I spoke to. She then proceeds to cancel the so called subscriptions and tells me that my account is now clear. I have to contact the online companies which are deducting the airtime. At this point I lose my patience and ask her how I am supposed to call people I don't know and secondly with what airtime because I'm left with almost nothing. She asks me to hold while she discusses the matter with her team leader. She then returns to tell me that her team leader is busy an will give me a call later. In the meantime I will be received R100 airtime from the network. As suspected, the team leader does not phone and no R100 airtime has been transferred. I again phone only to be told by another call centre agent by the name of Khanyisa. She again checks and says she has found another subscription. Mind you, this is after I had been assured that everything has been cancelled. She then asks me to hold while she discusses the matter with her manager. After a few minutes, I'm told that the manager says there's nothing they can do. In other words, Vodacom has basically told me to go ***** myself as "there is nothing they can do". Nxa I'm so ****ed off. I told them to cancel my contact and ensure that it doesn't get renewed in June. Then, I was told, man you have to phone back on the first of May, as there is nothing we can do at this point. Really!!! What ****ery is this???
