Ordering of a gift online for delivery

I have had the worse experience with Netflorist today. I have been on their website since 7.30am this morning trying to place an order for same day delivery. I am in jhb and need to order a birthday gift for a relative in Durban. When choosing a gift that I liked, I kept on getting an error that there is issues with my order details and that that there is no stock of what I chose. Many different gifts was chosen and I kept getting the same message "no stock of the item". I have on the phone and have called the call centre over times. I managed get an item of my choice. And was with the consultant on the phone, I had to make payment via EFT and was asked which bank I use, I told the consultant which bank he said he should not be an issue and was given Netflorist banking details and was told that once the payment is made I should email *** with POP and the order will be released and delivered today. I then receive and email from the payments department saying that they have received my POP, however because the amount of my order was above R500, they unable to delivery as the funds need to reflect in their account. No where on their website does it says any off this. I am so disappointed as today is the relative's birthday and was expecting delivery today. I will never recommend Netflorist to anyone going forward. I will be sharing my experience on Hellopeter as well.
