I guess that really would depend on the type of 'help' you requested from them. If it was, say, in the field of, I sent a document, but CIC insists I didn't, then I can see how they might be able to help, however, based on what I "THINK" the OP is asking about and what you are stating here are two different things.
I THINK the OP wants to know if he can call on his MP at some point to help push his application along when he feels enough time has passed. That is obviously not the case for what is in the scope of an MP's power. I am sure you can agree on that, since you stated you contacted them at roughly 12 months and it appears your file took about 23 to complete ...
If I am mistaken and the OP just wants to know how/when to contact his MP to have a 'chat' about his application and the process it undergoes, then certainly, he/she may in fact be quite helpful. But for the majority of folks on this board, when they call their OP with 'complaints' about how long the process is taking and they are not out of the stated timeline, then the usual response is 'I am sorry, there really isn't anything I can do for you, please wait until the stated timeline has passed" ...
