Refusing to refund a voucher without reason

I've purchased 2 sets of DVD's from [URL Removed] using a Promotional voucher R250 and adding in R100 of my own.<br> the DVD's were received and did not play on SA dvd players due to the Region not being correct, I returned the DVD's and Kalahari responded saying they will refund me. <br> I have not yet gotten the R100 in my account which I am fine to wait 5 to 7 days for. <br> When calling into the contact center, I've been told that Kalahari will NOT refund the R250 voucher as it was promotional.<br> When asking Ricardo Sagewis WHY do they not refund promotional vouchers, his reason was \Because its promotional"which is a completely ******** and unprofessional statement to make. Clearly the staff do not know why they do not refund promotional vouchers. And a person in a Supervisory position has not taken the time and effort to find out why not. <br> I was not satisfied with Ricardo's reason and politely asked for his managers details or the call center heads details as I would like to have a better explanation. Ricardo point blank refused to provide me with anyone's details. He told me directly that he CANNOT give me anyone else's details. This is in direct contravention of the CPA!"""
