I just wanted to post here as well after being lock out a few days ago and after making a post on the forum looking for help.
A few days ago I was lock out I sent a customer support request I got a e mail yesterday saying to try again with a diffrant c card so today I tried my Credit card my wife credit card from the same bank after 2 error 401 I tried a new credit card got error 401 again then I try it again then I got error 601 and now it's locked again for 48 hours .

I talked to my bank they seen $1 preauthorization a few times even the new Credit card shows a preauthorization for a $1 I asked are they stoping them from taking the money they said no it is fine on there end it's just not being taking out they said so a few days ago some one on the forums told me to get a Ultimate game card try to add it it will show a error then call the game card ppl up and have them add it to my account so am on my way to wal mart and going to pick one up and try that I just hope SE get it's fix before next month I will let every one know if it works or not becuse waiting another 48 hours I will be disappointed because my wife can play but I can't
