CELL CUTS ME OFF 2 DAYS EARLY

So after my 2 year contract ended i cancelled my contract for 1 September 2015 , but Cell C decided to cut me off on the 29th ...... i have or should i should i say had 4000 free minutes and a few gigs of data left on my contract that cost me 1k per month . <br> <br> When i called the call center i was told , we are not sure why or what happened but we will email a supervisor and see what they say , We will come back to you ... that was over 8 hours ago no word from them at all.<br> <br> I cannot believe that after taking more than 24000 rand from me you have the audacity to cut me off 2 whole days early ~~~~<br> i will be seeking legal advise
