network communication longview texas. Beware of Their Fraud !! Internet

Beware of this company. If you happened to use a pay phone at the airport or something, you will get charge $30/minute. I found out by calling their toll free number, after I found out about 3 charges in my account that I didn't know off. I got 3 times charge of $30, total of $90. And I never use pay phone, there's hardly any pay phone at mall nowadays.  Good thing I always check my online statement. So, I can dispute this charge right away through my bank. I didn't authorize this charge, never authorize this charge. Someone probably use my card as a fraud in a beginning. But anyway $30 a minute ?? It's a rip off, and it's a fraud. Let's sue them.
