VODACOM NOT DOING THEIR JOB!!! ***********!

On 1/08/15 at 11h20 I bought 1 gig data for my cell number. I made a mistake and purchase it monthly instead of 30 days only. I immediately online chat with Vodacom who informed me to contact or email the Call Centre. I decided to email the call centre in order to have proof of requesting the cancellation with immediate effect. <br> I emailed to [Email Removed] on 1 August 2015 at 11h29 with the heading Cancellation of data bundle. I received a mail back from the Customer Care with reference 004K-K1UB, stating that someone will contact me within 24 hours. NO ONE CONTACTED ME. On the 18/08/15 at 08h06 (15m28s) I contacted 111 again to enquire if it has been cancelled. The lady told me it has been cancelled and she can see it on the system. I did not take her name or ref. I received my bill at month end noticing it has not been cancelled as I was billed. I phoned again on 03/09/15 at 08h07 (36m55s). I spoke to Zama Xulu. He told me it was not cancelled. He said his manager Joyce Morokang is going to investigate and phone me. I am STILL waiting for this call! ***. I am STILL paying for something i dont want!!!! I cannot help it is loaded on my phone!!!!!
