********** Activity on my Vodacom Account - No response from Vodacom!!

Good day. By way of background and in short, a new Vodacom account was **********ly added to my existing Vodacom account at the Vodacom store in Game in Ballito Bay (together with a debit order on my bank account for the ********** account)!! I reported this ***** on my Vodacom account to Vodacom's ***** Analysis Department (as requested by their Call Centre) on 16 October. I have sent numerous emails in this regard to the ***** Analysis Department with all the supporting documentation on request of the Call Centre. To date, I have received NO response whatsoever to any of my emails (despite receiving read receipts, indicating that my emails have been opened and read). I have also tried to call the number given to me by the Call Centre for the ***** Analysis Department but it either just rings or is constantly busy. My November account still shows the ********** activity!! Besides from assistance from one of their contractors from Merchants (who has indicated to me that he, too, cannot get hold of your ***** Analysis Department and so he cannot provide me with any information), no one has bothered to return any of my emails. I even posted my complaint on Vodacom's Facebook page, was told that I would be assisted but NOTHING! I am appalled at this shocking service (or lack thereof) that I have received from Vodacom. I have been a paying customer since 2002 and I would have expected an immediate response, given the nature of my issue. I would really appreciate some input as to how this can be resolved as a matter of urgency. Many thanks. Wendy
