Yellow and White Sprinkles (3 oz)

I purchase in enough time for a party this weekend. I was excited to her that they came in and was looking forward to open the box when I got home. I opened the box and instead of Yellow and Black I got yellow and green. Now I am stuck. Sent an email on the 29th and did not hear back. I called and left a message. This is not my way of customer service ...... It's too late for me this weekend and now have to change plans pretty disappointed.....
