Has anyone else had a problem with payment of the supplemental? It times out in five minutes, and when it times out you cant get back into the payment screen. I pressed back on my browser, pressed submit again and it brought me back to the pay screen, which I submitted and got a conformation email from, but when I called they said that they hadn't received payment. I also gave their IT guy my conformation number, and upon doing so he said "I'll check that for you, good luck!" and hung up.
