Poor service from Outsurance and their panel beaters

I had an accident last year December and my car was taken to a panel beater Olympic Panel beaters with Outsurance it was a very painful stressfull process with their panel beater that it took 2 months for the car to be fixed.The panel beaters had different promises but no delivery.I received my car on Saturday they showed us the car on Friday outside where the damage was and all looked fine we did not bother looking inside as we knew the damage was outside. On Sunday morning we woke up going to church only to find out car is stinking inside like a mold. When we looked under the seats from the back only to find that the carpet of the car is now wrotten and has white things like mold and its smelling.When we took the car that day it was after a wash nothing looked or smelled wrong until the car dried up.My front bumper is not alligned properly the inside clips that hold the roof inside are missing the seats as well are dirty and stinking as well. Why are we paying insurance if we are going to be ********** by our own insurerrs that we trust and they cannot fight or protect us. I lodged this complaint this morning and was advised they will get back to me whilst l drive a stinking car its not affecting them its affecting me and my kids at the end of the day. With this pathetic service l advised Outsurance that l will not pay excess because of all this treatment l have received from their panel beaters but they couldnt care less l ended up paying the excess even though l got this **** service. All l want is for my car to be fixed properly as l pay their premiums without a fail why must l get such **** service with immature panel beaters who dont know how to treat customers and dont know how to take car of our cars.Who on earth does such cruel things?Im so dissapointed with Outsurance to think that l have been telling my friends that they are the best and this happens.
