No stock after waiting almost a month for feedback

At the beginning of March I app**** for the March special for the Mifi device with 5GB data at R99 per month. Not hearing anything for about a week a used Telkom's useless online chat to enquire if I could go to a store to get this. I was told it was only an online deal and they would get an online sale rep to call me. We received a call today 29/03 to say there was no stock. Sorry. I can understand the concept of \while stocks last\" but when applying at the beginning of the month when the deal starts it is ridiculous to not get stock because you are only attended to at the end of the month."
