Sprint Sprint Sprint's address said to be invalid on civil action suit...marquee looks weird Atlanta, Georgia

I file a civil action lawsuit against Sprint on July 10th 2009 and could not get the serve to go through for malicious reasons.  When I first filed they said I could not use the mailing address I had on my statement.  Right after, I called Sprint on the courthouse phone and asked for the Sprint corporate office next to Bank of America on Akers Mill but he said he doesn't know it.  I told him that the suit is for you.  I went to the  physical location of the Sprint corporate office right next to Bank of America on Akers Mill and he said that the address was 3065 Cumberland Blvd.  I looked at the marquee and it said 3065 Cumberland Circle, the circle address matched another record so I used that one.  I filed this one and it came back "no such address".  Went down to the first floor of the Cobb county courthouse and she said that was a valid address (3065 Cumberland Circle) and said I just left out the word "Club" (3065 Cumberland Club Circle).  I filed that one, took a pic of the marquee that said 3065 Cumberland Circle and emailed to the local Commissioner.  The new file of 3065 Cumberland Club circle still came back invalid even though a local police said it was Sprints and it is one of the addresses that they use.
