WAITING ON A REFUND SINCE 1ST JUNE 2015

I have cancelled my contract with Vodacom in April. They however still debited my account for the month of May. When I contacted the call centre they advised that they would pass a credit. I never received it and when I contacted them again they told me they credited my Vodacom account. <br> <br> WHY CREDIT A CLOSED ACCOUNT????<br> <br> On the 4th of June I received an email telling me it will take 7 working days. I to date have still not been refunded and today a consultant told me that my refund if pending!!!!!<br> <br> Reference numbers listed below:<br> <br> S3-85C3J-JUP6F<br> A6-WWJU-M61YT<br> S3-881A5-5W6O<br> 001B3aAS294CH0S6<br> <br> Can someone please just credit my account with the money that is due to me?
