Cancelled contract without my knowledge

<p>Good day</p> <p>I've been a loyal customer to vodacom sa for many years. Yesterday I found out that they cancelled one of my contracts without my knowledge. After several phone calls to vodacom there is no sucess to re activate my line. They told me that the line was cancelled november 2016 but I upgrade on the exact same number in Des 2016. How can they upgrade the number if it was cancelled? I need the line to be activated as soon as possible or I will move all my contracts to Cell C or MTN. Can someone please phone me regarding this matter. I need it to be sort out today!! This is a mistake from vodacom side and now they gone loose a loyal customer if the problem is not going to be fixed.</p>
