Sadly even the MP can't help in some cases. They gave the MP the exact same answer they were giving me
Wow, that's not encouraging on their side at all.
From my experience contacting the MP needs some crazy steps. When we 1st contacted the MP this lady from their office had taken down our info promising to attend to it. I then asked my wife to call them again and imagine this lady had taken leave js the next day to resume the following week. Asked me wife to be convincing on phone how its important and affecting us. So the new lady took it on priority called ircc sharp wf a response. Unfortunately MP said my file is almost done and hence they can't do much but they would try their best. She gave us some bit of explanation from IRCC as to why it takes longer, something about background checks and stuff. She gave us her personal email to contact anytime we have inquiry or are bothered about something. We are just waiting now as she kept us calm.
So I guess it normally depends on who handles your query at the MP office. The first lady kept telln us to not expect much as many people are in our shoes and hence can take longer than expected, and this was when she hadn't even made a move and also went on leave the following day. We improvised and got intouch with an angel.
Not sure if this experience helps but you could try them again with a compassionate email on how yall worried.
