OK, then let me try to help you. Did you send in an order form for the 4th shipment? If so, he might send it, but it can take up to a month. If not, just send in an order form and don't worry about e-mail. He's not good at e-mailing. If you order, or have ordered, and don't get, then it was either seized (not too likely with biotran, but does happen)or he's written you off for being late in payment. As others have said, it's his way or the highway. I hope you get your meds.
