No delivery of prize

I bought Energizer batteries in Dec 2015,entered the promo competion and won.I called the next day and spoke to Virginia.She said that I did win and that she'll call me later,she didn't.I called and there was no reply.I called back a week later and she told me that I won a Russell Hobbs blender and it'll be delivered in the 3rd week of January.On the 22nd of Jan 2016,I called her and she said that blenders are with the couriers and that I'll receive it next week.It's the 10th of Feb and there is no delivery or any contact from Virginia.Why run a promo when you'll can't keep to your promise?
