A Charlotte grandmother is fighting a wireless bill of more than $10,000 that was boosted by six weeks of calls to an adult chat line.

Opal Savage told The Charlotte Observer she's not responsible
for the calls. Verizon Wireless has said in correspondence to
Savage that the calls were made from her phone.

Savage said she bought the phone for her two grandsons, both
teenagers during the period in 2006. The two have sworn they didn't
place the calls, and Savage notes that most of the calls originated
between 15 and 30 miles from their Clinton home and that some of
the calls overlapped in time.

Most of the calls went to Secret Encounters, an adult chat line
based in Granada.
