Is Amex tightening up churning or am I an idiot?

Every credit card app I get a call as there is a credit watch on file due to cc fraud many moons ago. So Amex call and I give them my home info instead of my biz info I used for the biz SPG card app. Legit biz too. Anyway the agent who called puts me on hold...at the 10 min mark I hang up. I called back later in the day only to be told my app has gone to a diff. department. Don't remember what it's called but I called yesterday and they denied me!!!!!!!!

And last week PC Financial MC took my $12k limit to 1K, ...? I did have $50k owing to Amex back in Feb but it was all paid on time, maybe it's hitting my file?? Amex told me to wait 3-6 months to reapply. I assume it's ANY AMEX card? Looks like I'll be busy when I get back from vacation. There is a little consolation on my Gold card as I hit $1.5K
