Update: heard from someone in exec office who apologized no explanation as to what happened and said they were giving us each an additional $50 obc, i.e. $100 for the 2 of us for a total of $200, but that would only be an extra $50, which us what the cruise planner showed. I emailed the person again and reminded her to look at the original confirmation which was attached to the email. The original obc was $150. Someone else responded and as of today I have an apology and the correct amount of the obc. The explanation is that for an unknown reason our original obc had dropped off. Of course no explanation as to why they dropped off. I guess it was just Royal IT.
