Inadequacy of Vodacom

This has persisted for three months now. It all started on the 27 May 2015 I went to pay my vodacom accounts which are two different ones under the same Identification number, my own. Went to branch at N1 city, as it and Tygervalley are only branches to pay at. They were offline and had to do a manual payment, we proceeded to pay the account. I told Daniel the service consultant that the amount paid was for both accounts and he acknowledge that and assured me that he will do it. Nevertheless that didn't happen resulting in one of my accounts going into arrears. The following month I made a payment arrangement which was all vodacoms fault but is now my problem, I went to pay cash and they still debited my account so double payments went through. Tried to get a refund and after each staff member I speak to on numbers 082111 (Customer services) and *** (Credit and collections) they either give me the wrong information or log my request and nothing happens, I'm still sitting waiting for my refund. Which is an amount outstanding for another creditor and this has lead to June and July arrears amounts with them. I spoke to Tramain Chapmann today and she just put the phone down on me.
