We do apologize for any frustrations! I have tested the unsubscribe feature within your account by adding and unsubscribing myself. It seems to be working properly when tested. Are you getting any specific feedback as to what people are having trouble with? Are they receiving an error message of some sorts? Again, we do apologize for the frustrations but if you can provide us any more information into the matter, we would be more than happy to troubleshoot the matter for you further!
