Wow Momo's — service

I ordered 2 veg and 2 chicken momos. Usually sauce is given complimentary with momos. So i asked them to give, receptionist said it's already inside the box, i said fine. But when i opened boxes, none of the 4 had sauce in it. Such dishonesty was really not expected. Wow momo's should really think how cheap they are projecting themselves by doing this kind of act.
