my company has responded to every call what might be happening is the ones that are not are already tired of the guys who call for a job that want the world with a motel room and purdium etc. etc. also tired of all the guys that say im clean i can pass the background and u/a come to find out after they spend all the money to background check and drug test that the applicant is either a felon or is positive for meth or thc or all three but i do agree the companies that dont bother to list a # or contact name shouldnt waste anyones time but also dont waste ours if you know you dont qualify
