is PB Mining typically slow at responding to emails and such?

I have emailed several times about my Bitcoin address with no answer, and I have placed an order almost 24 hours ago and it hasnt been actioned. I tried two small tests and they went through very quickly of 20GH and 50GH. But the 500GH order has been hanging there.

Hoping it will all get sorted. Its my first foray into Bitcoin, hoping that some of the content in this thread isnt true.
