No feedback

I have been without my car now for more then 3 months. I received feedback only in the first month when I claimed. Now, numerous emails sent to Momentum, only time I got a reply was when I said I'm going to cancel. I am getting feedback from the company that is busy with the repairs, they confirmed they are also not getting feedback from Momentum. I am sure it's understandable that I am beyond upset and angry at this point, using Uber/online shopping is not cheap and I am a single mom ... without a car. How am I suppose to afford Uber to work every day? How can it take so long to repair a car???????
