So I got my AMEX blue preferred this year.
They gave me a stupid SL of $ 2000.
This june, I request online to increase to $ 6000 which was approved.
But today I received a letter from AMEX that effective immediately my new CL is $ 20k.
What?!?!?!?!? I DIDNT EVEN ASK FOR AN INCREASE. and I already ask for $ 6k last month. Holy. Weird….. Explanations ?
