We constantly get calls from this #, caller ID shows "Newhall" but when you try to call the # back you always get a busy signal. This is from a company by the name of Dynatek Industries in Santa Clarita, CA. and they are soliceters. When i do actually take the phone call i immediately advise them to remove our compnay contact informaton from their database before i can get 3 words out they hang up. If you get calls from this company and wish to have them stop call 800.960.1138 (email: email@example.com) and advise them to remove your information.
