Golang: reflect.DeepEqual returns unexpected false

I have the following code and code test below and for some reason the deepEqual is returning a false and failing the test. Now from reading the doco on this I would expect this to pass with a true for something so simple? Any points would be much appreciated. Thanks

// customer.go
type Customer struct {
    customerID int
    domains []string
    names []string
}
func NewCustomer(customerID int, domains []string, names []string) *Customer{
    return &Customer{
        customerID: customerID,
        domains: domains,
        names:names,
    }
}

// customer_test.go
func TestNewCustomer(t *testing.T) {
    expected := &Customer{123,
        []string{},
        []string{},
    }

    got := NewCustomer(123, []string{}, []string{})

    if got.customerID != expected.customerID {
        t.Errorf("Got: %v, expected: %v", got.customerID, expected.customerID)
    }

    if reflect.DeepEqual(got, expected) {
        t.Errorf("Got: %v, expected: %v", got, expected)
    }
}

output:

Got: &{123 [] []}, expected: &{123 [] []}
