Im September 2017 applicant, in process since November. I called CiC after full 12 months and they told me that if i dont get anything by December 14 i should contact them and find out. LOL. Like are you serious?! December 14th laterally few days before Christmas and new year which means they gets holidays and they don't really work around that time.
Im not really planning to call MP. I feel they have nothing to offer. It's just a mess. Best thing is to keep in touch with the CIC themsleves and if anything finding an immgration lawyer for free since my College offers free legal services.
