I sent you my payment on 04/13. Unlike all my other payments (which cleared in three-to-five days), this one did not post until 04/28-- over two weeks later.
You refused to reverse the $35 late fee because you reversed one as a "courtesy" in January when your first bill to me arrived the day after it was due.
When I called with a rep from my bank, you still refused to do anything. But you did try to sell me gift certificates! That made everything better! :D
