Online shopping .. no delivery

On the 4 April I went onto the netflorist website to order flowers for my sister in Gordons Bay for her birthday. The next delivery date would only be on the 7 April, I was fine with that and placed the order and I received the sms from the bank saying the debit was made and all was fine. On the 7 April in the afternoon I called netflorist to find out when the delivery would be as my sister did not receive any flowers. After holding on the phone for 20 min I was told they would call me back. On the 8th I called them again as no one called me, I held on for another 20 min and when my call was answered again I was told they would follow this up and call me back as they could not see my order. On the 9th I called again, I was told the problem was with my bank and I had to call them, I called my bank and they said everything is fine on their side and gave me an auth number. I called Salome back and she said she did send in a query and she would call me back. On the 10th I had to call them again and this time I had to send them my bank statement to prove that the payment went off. I still have not heard anything from them. I am angry as no one is getting back to me.
