False advertising and Rude Consultant

I’m highly disappointed with the service that I received today.... I ordered an item online for delivery in KZN today. As I normally order from Netflorist I made my selections and looked for items available in that region. I paid for my order, emailed proof and was waiting the confirmation of the goods being delivered. Only to receive an email saying my order won’t be delivered and a consultant will contact me(which never happened as I had to make the follow up call) I was told that the item is not in stock and they could not give me timeline as to when it would be delivered. I accepted that, asking the consultant to find out when you will have the stock of the item and give me a proper delivery date (which I think is only fair) The consultant calls me back a hour or so later saying that there is no stock of the item, it never was available and is not going to be available! Here’s my issue with this... why was the product advertised if it’s not available, and in return I am offered a voucher or refund. The thing is I don’t want a voucher or a refund. I live in Johannesburg and I am trying to send an item as a gesture to a colleague who lives in KZN how is a voucher going on o help me? I’m highly disappointed that not only won’t I have a delivery today, there is also no possibility of it happening anytime soon! Not the service I had in mind... and I wouldn’t want to escalate this, but am not getting any joy from the consultant that I spoke to!
