Tried to enter sweepstakes. Kept coming back as error. I checked numbers. All correct except last three survey numbers. I corrected them and reentered. Error again. Your system changed them again. I tried three times, all the same. Changed from 170 to 070. Something wrong with your system needs to be fixed. Soon! This happened to me about eight months ago also, last time I tried. How is this so hard to fix? It’s your job.
