Unexplained R500 data usage on final bill after closing contract

<p>I had a R199 p/m data contract (5GB+15GB) [Acc. ********** 70] for many years.<br />I phoned the call center on 26 July 2016 to cancel, giving Cell C the month notice.</p> <p>In September I receive the final bill with an unexplained R500 data charge added.</p> <p>On 12 Sep. I spoke to Mbali in the call center asking an explanation. Ref: ********** <br />Since then I spoke to the following people asking them the same question and till date I have NOT RECEIVED any EXPLANATION from Cell C: <br />2016/10/14 - 9:27 - Sphiwe</p> <p>2016/10/14 - 9:33 - Lunga Magola</p> <p>2016/10/14 - 9:37 - Noleen Chetty</p> <p>2016/11/15 - 8:30 - Nadene Lukas</p> <p>2016/11/15 - 8:52 - Femone Laurence</p> <p>2016/11/29 - 8:34 - Portia Mobipa</p> <p> 2016/11/29 - 8:45 - Thabo Mbatyazo<br />Thabo wrote me an email with a new reference number: ********** ********** 42.<br />It is another week later and I have NOT RECEIVED any EXPLANATION from Cell C.</p> <p>It is truely *strange* how additional data usage is exactly R500. Also given that on this contract I have never and COULD NOT go over usage. In the past, it will just stop if I used up my data (as expected). So Cell C, please explain!!!???!!!!</p> <p> I want to know:<br /> - What date(s) did I use that data?</p> <p>- How much data was used?</p> <p>- How was the R500 amount calculated?<br /><br />This is truely TERRIBLE CUSTOMER SERVICE if they cannot answer a such simple question about one line item on a bill and this is now going on for 3 MONTHS! </p>
