Nawlins A/C | Stefan Gaszak Did not complete job and stole my money New Orleans Louisiana

Stefan Gaszak quoted me $9,500 to install an A/C system for a home I was renovating.  After paying for the job in full, the company literally dragged the job out for a year and promised to complete it on a weekly basis.  After a year had passed, Stefan told me that money had been spent and that I would need to buy the A/C units myself at a local A/C supply house.  I ended up spending $1715.37 for the A/C units after I had already paid the balance in full plus $500.  Stefan delivered the units to my location, but still did not complete the job and I had to pay another A/C contractor to complete the job.  Stefan told me that the units were covered under a 5 year warranty.  Well, one of the blowers stopped working last month and Stefan has promised me multiple times that he would repair it under warranty.  A month has passed and he has still not fixed the issue.  Now he is not answering my calls.  I sent out another A/C contractor who told me that the control board was bad and needed to be replaced.  I called the A/C supply house and they told me that Nawlins A/C needs to handle the warranty and that it cannot be done by the home owner.  I am not out of $3300 above what I was originally quoted and my A/C system is still broken.
