Freezing Of Aldi Tenderloin Steaks

I buy 12 or 14 of the Cattlemens Tenderloin Steaks at a time for my freezer. Yesterday I was pulling some out of the freezer and the date on the package was 9/111/13. There are spots that look like mold inside the meat compartments. Almost like the package wasn't sealed right when packaged. I want to know what all the little "green" spots are. I hope this isn't mold as I buy these all the time for my freezer and they should keep longer than this. I have frozen them before for 6 months and they were fine. Never had a problem with aldi meat and this was really scary. Do I take them back to store or what????
