A gews years ago my cell phone started ringing off the hook with callers asking if I fixed air compressors. I contacted the company and it stopped. Now, out of nowhere they are calling again! Why do they only have one number listed? Why is it a cellular number? Why arent they worried about all the lost business? Sounds nothing but shady to me. I can only tell you that ic you call them, I will answer and I dont have a clue what air compressors do!
