Disappearing Data and lack of Service

This morning at 00h05 my data started disappearing without me using it. Within one minute my data went from 50mb to 0 (zero). I called vodacom to enquire, they told me my account shows 'normal service'. I have proof of messages and times that were sent indicating my data disappearing, I offered to show them these messages but they were not interested. I then asked for a cancellation of the contract. I was told that the cancellations department would call me back after 8am which they never did. I called again but I gave up because the phone was not answered. I called again for the third time. I spoke to a guy who just hung up on me without hearing the rest of my complaint. Last mouth my data disappeared and that time I was given free data in compensation, earlier this month my *111# service did not work and my network signal did not work, all I got was a lousy apology. I am very upset and I am leaving vodacom with no turning back. I want everyone to know and to avoid being victims of such bad service.
