Refund of my account

I cancelled my account with DSTV 4 months ago, and still had a credit of R2002.00 with them.<br> Ever since that day I have been struggling to have them refund my money. They have my account info, and my account with them clearly shows the R2002.00 they still owe me.<br> <br> I have been calling them in all this time, and no one is taking responsibility for this.<br> <br> The supervisor Khumbulani Zulu and I have been in contact via email, but still the problem has not been resolved.
