Double charging subscription and NO refund!

<p>I upgraded in April this year (2016). At the end of May, my account was double charged with the subscription for my contract. I contacted the account department on the 6 of June and they confirmed the double charge. I received a sms that my query was escalated to a support specialist. On 9 June I received a sms that they are aware of the subscription double charge and apologise for the inconvenience and will correct the error and ensure that I recieve a credit note. I also recieved a sms informing me that my query was now closed. Up to now, I have not received my money back or seen it deducted from my account. I also contacted the account department on 30 June, 2 August and again on 30 August. Every call lasted between 20 - 25 minutes with a consultant who was not able to solve my problem or put me in touch with a supervisor. All these consultants promised to phone me back the next day with a solution for the problem. I never received a call back from any of them. Vodacom can deduct money from your account and then it becomes YOUR problem to get the money back from them, but don't you dare miss a payment and your line will get blocked. Vodacom, you should be ashamed of the terrible service that YOU and especially your call centre staff provide. Shame on you!!!</p>
