I applied for a credit card and was turned down due to “sufficient open lines of credit.” Isn’t that a good thing? My credit score is around 809.

You scored low because you have been applying everywhere and your credit has been check to many times in a short period. (It makes your score go down.)

You already have two or three lines of credit from that source. Even though the issuer has different names, it is the same bank.
