Refund outstanding 6 months later!

On the 28th December 2014, I attended the international food gourmet show in Cpt. We bought tickets for the kids, which were announced to be free of charge on the day. I enquired about the refund on that day and I was promised computicket would handle it. 6 months later I am being avoided about this. The last I heard was that there was a dispute around my refund, when I asked for feedback Ms. Valerie Nagooran, who is the call centre supervisor, went AWOL. I will escalate this to the highest of powers as I believe I am being ****** of R400 for both kids. What is annoying is that she mentioned that a lot of people who were in the same situation had been reimbursed, if so why am I not yet paid back? I have been at constant contact with Ms. Valerie, until she decided to avoid my e-mails. I have also requested at numerous occasions to be given the Sales manager/customer care department contact details, to date she is still avoiding to give me this information. Please Computicket do what is right and pay back the R400 you owe me. Thank u.
