printdata.uniq is the same items as printdata, because printdata only
contains one item. So you're doing this:

   dateCheck = ["string"]
   printdata = [["string"]]
   @alerts.push [["string"]].uniq

I don't how deeply nested you want your arrays, but if @alerts is the
final product and you want it uniq, you could run @alerts.uniq! at the
end, or do something like:

   @alerts.push printdata unless @alerts.include?(printdata)
