no reply when I answered

No one there when I answered, or at least not talking to me.  Called back and it went directly to voice mail only stating the phone number.  Caller ID says it's a wireless caller.

This time someone was there when I answered claiming to be Tucson Auto Glassworks.  I asked why they were calling since I am on the Do Not Call Registry.  They said they would eliminate me from their list.  There is no such company listed in Tucson so I don't know if they were just an auto glass organization or were from a specific company.

This group has called me many, many times saying that it is a auto glass company.  I have told them that we don't need any auto glass and to stop calling.  today they started calling and not saying anything when I answer.  They called four times today with no one answering each time.  They sometimes call every day or at least a couple times a week.

Just rec'd a call from 520.289.0494 and they said they were Tucson Auto Glass Company.  I asked if they were telemarketing and they said no.  I told them not to call.  When I tried their number it just rang and was forwarded to voice mail - however the number that the voice mail gave was a 620 area code!
