The common aspect of these problems is people cutting things rather closely. That's not a good idea on any hot deal. Give yourself some margin for error, whether it be yours or the company's.
I had been holding large amounts of various hotel and credit card points for transfer after the first of the year specifically for early qualification for CP. I didn't want to delay the transfer in the event of a devaluation or, God forbid, a discontinuance of the companion pass benefit. The transactions happened mid-day on the first day of the year so I wouldn't consider that cutting things too close. I know I will prevail in this because of the records. Southwest made the mistake in this case but it will take time spent on telephone hold to rectify.
