"AlwaysOn" poor service and no data

Purchased the 2G deal for R99 and was deducted from my bank account but no voucher was received via email or SMS. When I called their call centre I was told they could not help me and that I should email their support team, which I did. 8 hours later and 2 emails in I receive a "****y" response to say that they have emailed me at 1:30pm (5hours after my initial email and that has mysteriously never appeared in my inbox/spam) and that they can't find evidence of my purchase. So I sent them my bank statement with prove of the transaction and which hotspot it was purchased at. No response has been received and no data. I will never purchase from them again and would not recommend them at all.
