Wow! I just got my business line hooked up and 2 days later the phone is ringing off the hook. I really doubt anyone from Arizona is wanting my services. So why would an Arizona and unavailable # be coming up on the caller ID? telemarketers. 12 calls in the past 6 hours. Almost every 45 minutes the same number is coming up and there is a second number calling too. Do business lines get to use the do not call list? Anyone have this problem?
