vlive

Hi, i am a Vodacom customer since 8 years and took an internet contract last year. I must say I hve now and then problem with the service but yesterday was **** the cherry on top. The word Call Centre and Customer Service simply doesnt exist in their dictionary. My problem started yesterday morning when i checked my data bundle. The last time i checked my data was the previous nite before i went to bed and swtiched my 3G off. It said that i had 148MB. The next morning when i switched it on and did some emails WITHOUT attachments and WhatsApp, my data was 6.60MB!!! SO i called the Call Center and complained. She said that i had switched on Vlive and that ate up my data. She also said that it ran through the night until 1 a.m...! The more i told the woman (forgot the name) that i have never heard of this Vlive, the more she said that i had it run through the night. I was like talking to the wall. I was in bed already before 10pm..how could i use internet until 1a.m when the 3G was swtiched off before 10pm? She said that i must go to Vodacom store to de-activate my Vlive....the questions are...How is it possible to activate Vlive without Customer consent? It's a **********
