You do not want to use poll() in your while loop because it returns the first element of the queue and removes it from the queue. Use peek instead so that you just test for the existence of a customer service rep within the queue.
Once you break out of the while loop, assign the first element in the queue to the csr using the poll() method this time.
Then call the csr assist method.
Then add the csr back into the queue.
Hope these hints help.
Regards,
Chris
