Can not get my code to pass!

I have tried everything, someone please help.

CallCenter.java 
import java.util.ArrayDeque;
import java.util.Queue;

public class CallCenter {
  Queue<CustomerSupportRep> mSupportReps;

  public CallCenter(Queue<CustomerSupportRep> queue) {
    mSupportReps = queue;
  }

 public void acceptCustomer(Customer customer) {
    CustomerSupportRep csr;
    while(mSupportReps.isEmpty()) {
      playHoldMusic();
    } 
    public void Set<CustomerSupportRep>assist(Customer Customer) {
      csr = mSupportReps.poll();
      csr.assist(customer);
    }
     mSupportReps.add(CustomerSupportRep);
  }

  public void playHoldMusic() {
    System.out.println("Smooooooth Operator.....");
  }

}
CustomerSupportRep.java 
import java.util.List;
import java.util.ArrayList;

public class CustomerSupportRep {
  private String mName;
  private List<Customer> mAssistedCustomers;

  public CustomerSupportRep(String name) {
    mName = name;
    mAssistedCustomers = new ArrayList<Customer>();
  }

  public void assist(Customer customer) {
    System.out.printf("Hello %s, my name is %s, how can I assist you.%n",
                      customer.getName(),
                      mName);
    System.out.println("...");
    System.out.println("Is there anything else I can help you with?");
    mAssistedCustomers.add(customer);
  }

  public List<Customer> getAssistedCustomers() {
    return mAssistedCustomers;
  }

}
Customer.java 
public class Customer {
  private String mName;

  public Customer(String name) {
    mName = name;
  }

  public String getName() {
    return mName;
  }

}

Nested methods aren't a feature of Java (though you can create similar constructs), so declaring a new assist method won't work. It's also not needed; The assist functionality is built into the CustomerSupportRep class.

The rest of the code looks fine with the exception of one part which I've marked with a comment about the changes:

  public void acceptCustomer(Customer customer) {
     CustomerSupportRep csr;

     while(mSupportReps.isEmpty()) {
       playHoldMusic();
     } 

     csr = mSupportReps.poll();
     csr.assist(customer);

     // Put back the support rep instance instead of the class type.
     mSupportReps.add(csr);
  }
