Contract cancelled but Vodacom still billed me for 1 year and did not pay me back

I cancelled my Vodacom contract in June 2016 which was earlier than the 24 month period. I therefore paid the early termination fee. I requested that my number be moved onto prepaid so that I could port the number over to Cell C. I was told that all would be sorted. A few months down the line in September, I realized that my account as still being debited for the contract. I called the customer call center to find out why I was still being debited given that I cancelled and paid the early termination fee. I provided all the proofs and reference numbers and was told that they could not find the cancellation on the system. I then returned to the Vodacom customer center in Eastgate shopping Mall, where I had initially cancelled the contract and spoke the store manager. I explained the situation to him and he guaranteed me that he would sort it out and I would be refunded. December came and nothing changed as I was still being debited and I never heard from the manager. I went to the store but he was always unavailable. In 2017 I called the customer call center again to find out if anything on the account had changed and the news was that all was still the same. I decided to go to the Customer center at Vodacom World and explained the situation to the consultant. She confirmed that the cancellation was logged in 2016 June but was not sue why it was not cancelled and that they had my early termination payment on the system as well. She eventually cancelled the contract - finally! and was told that I will receive communication from Vodacom regarding the refund of the amounts that I was billed for about 12 months. It has been 3 and a half months since and I have not received any communication and / or an apology email for what they had done. The amount that Vodacom needs to refund me is approximately R 6 500. This is complete disregard for customers and is utter ignorance from Vodacom. Nobody could tell me why or explain why my contract was not cancelled either at the customer centers or the call centers, so I ask what is the point of these centers if they do not what is happening and cant help customers. Here again, honest paying customers are ****** without any communication and / or admittance of default on Vodacom's part. It is disgusting that this is how Vodacom manages their customers accounts. I do not recommend anybody enter into contracts with Vodacom as their service is pathetic and they have no clue what is happening. I have never been happier with my new service provider Cell C where I get what I pay for and am not charged for what I don't need. I am also on a contract with lots more perks at a cheaper price. Vodacom all I have to say is that I want my money. #Paybackmymoney
