Not calling back and not delivering my car

My car was in for repairs for almost 2 weeks, after i have received a call stating my car is ready and can be delivered to me, outsurance contacted me promising my car will be delivered. i arranged people to stay home and yet after calling Outsurance a few times nobody called me back. Saturday morning i called to find out where is my car just so that they can tell me that the Claim department doesn't work on weekend , i then told them can i get someone to assist me now. they put me on hold and then hang up. I will never use outsurance again if this is the way they treat there client and i will not refer them to any of my family or friend.
