Awaiting Feedback with No Reponse

I logged a issue with Vodacom Call Center. It was referred to Vodacom Back Office and I received a reference number. I was told that Vodacom will contact me in this regard. This call was logged on 26 July 2017. Up to today, 15 August 2017 I have received no feedback from Vodacom. I have phoned twice and I only get told that my request is still pending. It is a minor request and I don't believe that it should take a month to solve a query like this. Please can someone help me with my request, as logging an issue through the Call Center does not help.
