Waiting for refund 15days and still counting and Vodacom does not bother replying

After may account was wrongfully debited, I called in and yes the consultant I spoke to saw the debit orde4 and I was promised refund in 5 working days which was due on 7 November 2017. After I didn’t receive my refund I than called again on the 07-11-2017 and was than advised that my matter will be sorted out by 15-11-2017 ********** After receiving no update I called again today and spoke to Kagiso who made me feel like I’m some kinda of a fool. I’m very disappointed in Vodacom for treating me like this after so many years being a loyal client.
