Hey I tried to order and recived an error message about the merchant id being invalid. tried again and the same thing happened. Now it seems that you guys billed my card for both orders and there is no order reflected on my account at your site. I have been emailing you guys and no one responds. I want the charges reversed. This is a serious pain in the ass because I can't even order from another company because you guys used up my credit card limit. This needs to be fixed now. What if I was depending on you guys for my PCT chems?
