Turnaround time unacceptable

My car was towed to Renew It on 27.01.2016 after accident. I was informed the parts were received around the 15.02.2016. On the 23 Feb an sms came through to say car is loaded to repair system. On 29.02.2016 an sms came through mentioning the car is in paint preparation. On 02.03 I get sms one saying car is in paint preparation another one it is in painting. This is very confusing as I am not sure exactly what the progress is on the car. i have made countless calls requesting the Manager (Eddy) or Lana to investigate why it is taking so long to fix the bumper but none of the two returns my calls. Everytime I am told by the receptionist she will inform them it is urgent. I took back the rental car on the 26.02.2016 and asked Lana if she can organise a courtesy car as I stay in an area where there is no access to public transport and she told me they dont have cars and she wouldnt even mention to me by when or if she will make any effort to get me a courtesy car. It is unbelivable that it is taking Renew It so long just to fix the back bumper.
