Bought a voucher on Vodapay three months ago and never received it.

Three months ago I bought a voucher on the Vodapay app for R150 (they had a promotion where you buy a hungry lion voucher worth R240 for only R150 so I obviously snatched up the deal), only to not receive the voucher for THREE months. I've told vodapay on Twitter and they always tell me they're waiting for "feedback" which is a lie because they literally always have the same reply with no actual feedback on how to solve the issue. At this point it's like I'm the one annoying them even though I used my own money. I also asked for a refund and their reply is always "we're waiting for feedback from our team" I'll probably never get the money back, but just wanted to warn other people of my experience with their vouchers.
