Bad experience with budget insurance

My husband has been with budget insurance for over a year and half this year March 30 he had an accident we called budget everything was fine until they took the car on the 8 of April they even recommended a courtesy car because my husband has to go back to work,the took the car to a company called Renew it greenstone and told us we will be assigned a person who will tell us how far along the car will be there, and update us time and again,that never happened,the even told us that the courtesy car with be for 30 day but if the car is not ready by then, they will extend until the day the car is ready, never happened again,now it's past the 30 days of the courtesy car it has to go back they are telling us there's nothing they can do we have to return the car,and our car they've ordered parts but the will only come on the 22 because it's import,they never even told us this information we have to call ourselves to know this,we have been calling budget the whole of last and this week reminding them that the car must be returned on the 8 of May, there respond there's nothing we can do,now the car is gone,our car is not back we have no means of transport to go to work,I thought budget was the best insurance but I guess I was wrong I'm so frustrated with them,the thing is they don't even call you to explain, they tell us will get back to you before and of the day,for a week they've been saying that until they tell us to return the courtesy car today,we are just waiting for the car to come back after I don't think I want anything to do with budget insurance I'm done hopefully our car will be back fixed
