American Homes 4 Rent Maintenance Issues Indianapolis Nationwide

I rent a very nice home from American Homes 4 Rent in Indianapolis, IN.  I am a single parent with two teen age sons.  My 16 year old has a moderate severe case of Autism.  My refrigerator quit cooling December 20, 2014.  I have called American Homes 4 rent 9 times to have this fixed.  I have been placed on hold almost 3.5 hours.  A repair man came December 22, Tuesday morning, and said that he would have to order the parts but had to obtain an approval from American Homes 4 Rent to place the order.  That is the last I heard from this Vendor that American Homes 4 Rent has contracted with to repair my refrigerator.  I have had to endure entertaining out of town company over the holiday without a refrigerator.  It is a week later and after being told 8 times that the vendor would contact me, I still don't have a means of keeping my food from spoiling.  I am beyond frustrated and don't know what to do.   My budget does not permit my family to eat out every meal and my son's autism doesn't allow us to sit down in a restaurant three times a day.  I strongly encourage anyone else who is considering renting a home from this lousy company to RETHINK your decision.   I just don't know what to do.  We need a refrigerator which is a basic need, as is  heat and water.
