I'm Doug, and I'm very sorry to hear of your situation. My goal is to provide you with excellent service today.
Essentially, you have just a few options.
1. You can give them an opportunity to come back and complete the job.
2. You can accept partial refund if it will be enough to have a competent AC service come in and finish the job, or
3. You can file suit against the contractor in small claims
court for Breach of Contract
and present to the judge an estimate for the completion of the project and get a money judgment against them in that amount.
On the non-legal side of the coin, you can file a complaint with the Better Business Bureau
as well as with the state board responsible for licensing the company---though neither of these reports will result in you being mad while financially.
You may reply back to me using the Reply link and I will be happy to continue to assist you until I am able to address your concerns, to your satisfaction.
Please remember to rate my service to you so that I can be compensated for helping you.
I wish you and yours the best in 2015,
