This is ridiculous! I cannot get through no matte...

This is ridiculous! I cannot get through no matter what time of day I call! When I did finally reach someone, I requested the last possible payment date of the 28th of each month. Got everything all set up over the phone. Then I get my letter and the due date is the 22nd of the month!! This does not help me at all! I need the last payment date of the month and now I cannot get back through to anyone to fix this error! What a joke!

EDIT: I sent you an email. PLEASE RESPOND.
