Three days I sent in a request to change my subscription from one body type to another. I have received no reply, no acknowledgement, and I still got the old body type email today. When should I expect a response? Perhaps you could add a statement on the "contact us" page that "We usually respond within XX business days."
Back in the switchover to new website days, I also sent several emails over two weeks and got no response at all. Maybe something is still wrong with the new website "contact us" implementation.
