Northern star contracting services

I signed a contract to have my kitchen remodel. I gave a down payment of $5500 Plus another $5000 after they did the teardown of my kitchen. I have not seen or been able to contact the owner of the company or the two young man that did the tear down. It has been five days since they were here. I have called the company phone number plus one of the young men’s phone number. No answer. This company has been in business at the same place for at least four years. I have a feeling he will be emptying out his building probably during the night. Of course that is only my thought. I do not want anyone else to be scammed like I was.
