Horrible service

I have spoken to vodacom 5 times today for the same problem, my data and airtime just diminishes without me even using it. Everytime I load airtime and purchase data within seconds it's gone. I spoke to Felicia in the morning who advised me to go to a vodacom store for them to check the problem out. I bought airtime and data after I spoke to her and it got depleted again. I called again and I spoke to a very rude and unfriendly team leader by the name of YOLISWA who to be honest was very unhelpful.I then called back and I was referred to the technical department and the lady I spoke to refunded me, she even called back to check if I received the airtime.Immediately after I received the airtime I then bought data and again it vanished. I went to a vodacom store and the lady who assisted me advised there was something running in the background which I know I cancelled in June this year and I have a message confirming the cancellation and to my surprise it was still running. She then advised me I mustn't recharge my phone for 3 days, how do you use a phone without recharging it?I then spoke to another team leader by the name of Zee who said I need to go to Istore. I am being pushed from pillar to post and I'm not getting assistance at all from my service provider. So this simply means I cannot use my phone until I go to an Istore which unfortunately at the moment I am unable to go to. This is the 3rd time I'm experiencing this from Vodacom and quite frankly I'm annoyed and hugely disappointed in Vodacom if this is the kind of treatment they give their customers....
