Advertised but no stock

Upgrade time for me. Last month (June) there was no stock of iPhone 5c, and I was told there wasn't any left in the country. Yet this month, again advertised at an ever lower price. I assumed this meant stock had come in, so I went in today (Saturday 12 July) to do my upgrade. I was told there was no stock anywhere of the iPhone 5c. There hadn't been any stock arrival. Annoyed, I thought a second option would be an iPhone 5s, even though that was more expensive. There's no stock countrywide of that either, nor the 4s. I can have the iPhone 6, the only Apple product available. At R200 more that what I can spend. Your false advertising is purely to lure people into spending more money than they want. There wasn't ever going to be stock of those items, because a staff member confirmed they are run out items. So why advertise what you know you don't and won't have? Clearly not a mistake, because by the 12th of the month there would have been a correction made by now. It's false advertising! You cannot do that. I want an blue Apple iPhone 5c for the advertised R249 per month. 16GB. I would even take the 32GB. That is what I can afford and what I want. Else I leave to another provider.
