No response and communication

I was involved in an accident early February this year where a client of First for women smashed into my car. I submitted an quotationto to the lady and she submitted it to her insurance (First for women). She submitted the quotation on the 22nd of March 2018 and up to this day, she still hasn't received any feedback or information on what is happening with the claim. My car is in the workshop and payment needs to be done. The last information she got was that First for women is skeptical with the invoice. Yet First for women doesn't know the extent of damage on my car and they state that they don't send assessors for 3rd party.
