baller4life thanks for the shout out !!
Here is what happened to me OP: I was frozen out of my RITZ ard in Feb, 3 months post opening. Mine happened due to a Cash advance oops! However, after calling UW Several times, I was able to get a Sr UW to review my account ON THE SPOT -- and immediately was inofrmed account will remain ACTIVE based on my good credit score (715 if i recall), history with Chase and overall CR -- she even complimented much of my credit. She said it was flagged by computer for "odd actvity / Cash advances" .. no idea what flagged you, but Id suggest this is one time TO CALL UW -- do not wait it out, i see much worse outcomes for those who dont have a chance to explain themselves ... id call asap, and report back -- ASK FOR A SR UW or Analyst !!!
BEST BEST OF LUCK !!!! Just be honest with answers and polite, and im sure you will do ok. For many who did not call ive seen stories of CLDs and closures, so please call!
