Why should I pay for something I'm not getting

We as the consumers keep supporting suppliers that render us pathetic service, yet we choose not to expose them or complain because we are just to lazy to give a damn about our hard earned money being ******!<br> My Cell C Contract ended this month (September 2015). I cancelled it on the 4th August 2015. The consultant handling my cancellation told me my last debit would come off end of the month (Only comes off the 1st / 2nd of the following month). On the 3rd of September I saw that all my data had disappeared (almost 3 GB's), I called Cell C, they told me the 1GB was a special only running for 24 months and they had given me 100MB as of the 1st. Right, what happened to the almost 3GB's that I had remaining? The 5th of September I noticed all my data, minutes and SMS's were all gone. I had almost 3GB's of Data, almost 3 hours of minutes and about 300SMS's. Not even a warning, nothing. Now what do they do with all those hours, gigs and SMS's that you have paid for? Now I find out that I need to pay the full subscription of R400 for a service that was only offered to me for 5 days? WTHek??? THAT ISN'T FAIR
