Vodacom Woes

I am writing this review after experiencing extreme frustration and no explanation from Vodacom customare care. I have been a Vodacom customer for 12 years and for over 5 years have had 3 cellphone contracts. In all the years with Vodacom my bill has never exceeded R2500. Last month on checking my App my bill had escalated to R4000 and I have now been debited over R6000. I have done anything different or unusual. In all the years I have always received a message when my bundle was about to run out and I would purchase more data. Sitting with a consultant in the Vodacom store and going through all my smses nothing was received from Vodacom. Noticing my bill was getting out of control I purchased 1 Gig of data mid month which was used in one afternoon while my mobile data was turned off and I was in a WiFi zone. When voicing my concerns telephonically I was informed by the consultant that it was my fault as my apps were probably eating all my data and this typical of Iphones. He was extremely rude to me so much so that my husband picked up the phone to talk to him and ask him to change his tone. I then wanted to keep monitoring my usage. I went back to the Vodacom store to log a complaint which I never received any feedback from. Being paranoid I kept checking my Vodacom App to monitor usuage but each time I opened the App, it told me my bill was pending with no data available. I am extremely upset as you can imagine. I run a very small business and cannot afford bills of this kind! After visiting the Vodacom store for the 3rd time, a consultant assisted me in changing my contract to a top-up basis. She checked her records, found the complaint, said that it had been dealt with, but gave no explanation. The store manager couldn't give me a senior consultant number. I am so extremely paranoid that I may have been hacked, and my data ******. The consultant said I should voice my concerns on this website as someone senior in Vodacom will read the review. Sadly I am going to need to find another company to take over my contracts.
