No Help in 16days

I payed R19.00 for the Photography online course, money out on 16 January. I saw no voucher in my account so I called them.The call centre said nothing showed on my account so I must have used another account. I said i only have that account, he kept on that i must have another account because the transaction is not showing at all. I said i baught straight from the email i received from them from [Email Removed] and that's my only account. He said send proof of payment to support@daddys. I did and received a email with ticket number. Received another email from them saying ticket resolved, no payment received. After emails with my proof of payment, and saying the issue has not been resolved, I want my voucher, not even one respond, and I still did not receive voucher up to now. I tried calling again but there line keeps busy. It's not about the money, but about a course i wished to do, and the bad and dont care attitude towards there customers is shameful
