Citibank can kiss my ass

So I have all my bills set to be paid automatically. I check my statement and I realize my bill is late...this can't be so since I have it set to pay auotmatically. I look and the last payment was processed a day early. Therefore when the next bill was due it wasn't paid because on time because the payment I made was reflected in an earlier billing cycle.

So I call Citibank to resolve the matter. I've never paid my bill late in over 10 years so it shouldn't be a problem. I talked to the lady and we got the matter resolved fairly quickly. "I'll take the late charge off for you but don't you ever do this again." What happened to customer service? She reprimanded me like I was stupid and she was my momma. I'm like well isn't that funny. It was very early in the morning so I didn't flip out on her. I am just going to write them an email and just change my automatic payment date so I don't pay the bill too EARLY!
