I think they are flat out swamped and its not well organized. I left an email around the 5th and never got even an acknowledgement that they received it. I still don't have my GS package either.
I did call today about a flight credit and was told that there is a glitch for upgrades so they put upgraded flights on hold so their miles won't post. It should be solved in about 2 weeks. When I told them that their online system gave me a crappy error message and there is nothing posted or emailed to anybody and they could save lots of their time answering those phone calls by just proactively communicating the answer was : we just talked about this internal as well but nothing is happening.
For 1 missing flight credit I spent 10 minutes on hold, 3 minutes with a GS agent, another 5 minutes with her on hold trying to get mileage plus and then 6 more minutes for her to find my flight. If you add this all up you can understand the amount of calls they get.
I think they are just overwhelmed. And for a lot of issues it is not like you can just bring anybody in from the street that knows SHARES or the integration issues.
I am not sure though when overworked will turn into I don't care anymore on their end.

I have done many IT projects and understand fully well that this is a huge project and a lot of problems are to be expected. What I do not understand is the utter lack of communication or acknowledgement of problems on either the web site or via email.
