Vodacom empty promises

Dear Vodacom. This is like my fifth complaint. This is my last complaint before I forward to the consumer tribunal. I have a big problem.I asked numerous times for my airtime to be refunded back to me for the period last month and possibly early this month for airtime I used due to issues I had with my wi fi. I received at least two phone calls from a gentleman who promised that it would be refunded but according to my records I have not received this. I ask that you get this gentleman manager to call me directly to sort this matter out. I do not wish to speak to him but I want to talk to his manager. The name of the gentleman will be on the reference number under additional information. Please take note that this and other posts posted will serve as a formal complaint in which I will hereafter refer to the consumer tribunal. It has been now almost 30 days since I posted the first complaint. If this is not resolved it will be sent externally.
