Refund from Telkom Mobile overdue by a month

I bought airtime (R150) on 27-Oct-2015 via the Telkom Mobile website as I normally do using my cheque card. Unfortunately this time around the transaction went through on my bank account BUT Telkom Mobile did not credit my airtime.<br> <br> I raised this matter with Telkom Mobile via email. I sent them my bank statement as required. Stacey-Lee Du Plessis responded via email to say that I will receive my refund within 5 - 7 working days. It's now 2-Dec-2015 and I am still waiting for that refund.<br> <br> I have communicated numerous times with Stacey-Lee Du Plessis via email to notify her that the refund is still outstanding. She does not respond to any of my emails.
