Why am I "PRE-APPROVED" for a SMALL BUSINESS DELTA GOLD CARD ($50,000) when I can't even get a credit limit increase on the 2 cards I have now??? (BLUE and DELTA GOLD)...BLUE HAS BEEN ALMOST 4 YEARS WITH NONE!!! Why am I "PRE-APPROVED" for a SMALL BUSINESS DELTA GOLD CARD when my employer is a FORTUNE 100 COMPANY...AND I AM NOT AN OWNER OF THE BUSINESS (technically)
