Poor service delivery

Last year, I decided to cancel my Herbalife membership because of their poor service delivery. I met all the requirements to get back my registration money and till this day my money still has not been refunded, I have asked the person I joined under and she says that she is also still waiting for Herbalife. I have called Herbalife numerous times and nobody answers. I am shocked at their incompetence and I would not recommend Herbalife to anyone.
