I let my tall cup get fouled, white mold. Forget I am not washing it in bleach no way no how. I don't have a dishwasher so I can't sterilize it. I am trying to by a new cup, but the stupid online store loses my order as soon as I have placed it. I have already sent an email to customer support. It is 10:15pm PST, in order for my to talk to a real person I have to call between 8am and 5pm EST. I work from 8am to 4pm at a mental health rehabilitation center so for me to be on my cell phone at work is not really a possibility, so I am really FREAKING ANNOYED to have to call at 6am while I trying to get ready for work. Fix the online shop or add some hours for customer service.
