Poor response / lack of feedback

I won a prize on the 31st January 2016 and was advised on that day that my prize would be couriered to my home address and someone from marketing will be contacting me during the course of the week. After 2 weeks of waiting I sent e-mails to the marketing department. I eventually managed to get through to Roberta who asked me to forward the mail to her. After a week or so I received an e-mail from Arletta who said they were busy with fin yr end and the prize was sent to the post box. I thereafter sent follow up e-mails regarding the tracking number and why it wasn't couriered to my home as was indicated when I won the prize. I have not, despite sending many e-mails, received a response to this.<br> <br> I do not understand why I have to be the one keep following up and this makes me wonder if the prize even exists.
