Delayed Birthday Gift Delivery

I had bought a birthday gift for my sister on Netflorist on 26 January for delivery in Bhisho, Eastern Cape on 29 January. The time was perfect because I knew she would receive the gift in the morning of her birthday on the 29th. To my unfortunate surprise, I was called 29 January in the morning by a guy named Norman to tell me my package would only be delivered on the 30th because of a system error. Of course, I was highly upset but I tried to be reasonable because "things happen", so I made peace with it when he promised to have it delivered in the morning of the 30th and include a free box of chocolates in my sister's gift as an apology to me. Norman was supposed to sms me in the morning of 30th January to tell me that the gift had been delivered. When I did not receive this sms that morning, I called him on his direct line that I had requested the day before. I could not get hold of Norman on his direct line the entire day on the 30th and 31st January. I eventually decided to use the public line of Netflorist on the 31st and spoke to a lady named Nondumiso who told me that my package was only reaching East London on that day and would only reach Bhisho on 1st February. The package would be 3 whole days late. She confirmed that Norman had not added the chocolates to the gift package that would have been an apology to me, that I had asked to be added to the gift. Nondumiso apologised and asked to send me a voucher instead, which I agreed to, still trying to be reasonable as I believed it was Norman who acted ***********. Clearly I am naive because I am still waiting for that voucher that Nondumiso has yet to send me. To say that I am extremely angry and bitterly disappointed at the poor service at Netflorist would be an understatement. I did my part and ordered on time, but this blunder happened. I have never known Netflorist to have service like this so I am extremely upset. Netflorist is too expensive to give such poor service. For that matter I didn't care about the money because I was spoiling my sister on her birthday. Only today at 16:30 did Norman finally pick up the phone and of course I completely lost my cool. Now I want more than just a lousy box of chocolates for a gift that was sent three days late into the next month. It is completely justified. I got Norman's email, sent him an email and he said he is going to get back to me tomorrow.
