Running out of patience with WeFix

I booked in my Macbook Pro in July and I'm still waiting to get it back. I just get emails which says, "Your device is still waiting on parts. We are treating this with the utmost urgency and assure you that this will be resolved soon." This doesn't give me any estimate on when I will see my laptop again. It's been four months now, and I desperately want my device fixed. I also would like more information on why its taking so long, and I want an estimate of when it will be fixed. weFix Job Number: TVMC101751
