No response

I was in an accident in December 2014. I didn't send my car in for repairs in December as companies closed for the holidays. I got the claims forms and sent them in 2 weeks before it went in for repairs, from my understanding the assessor only went out to have look at my car last week thats after my car has been in for 3 ****** weeks with no response and NOT being kept in the loop. My car has been in now for a month which unacceptable for the type of damage my car has, once I called Renasa the didn't even know the correct amount of the damage until I had to correct her, I was also informed that I'll get generic parts for my car and not factory parts, I demanded that it will be original factory car parts to be fitted to my car, I pay for a service that claims to be good but think otherwise, I will not recommend Renasa as insurance company until proven wrong,
