One Call Communications - Navicomm Fraudulant Billing Carmel Indiana

On the day of 09/30/2005, I was billed for access to a site, which is unnamed on the bill. I was billed for $31.06 for 13 minutes at 19:57 hours on the date of 09/24/2005. I have checked all files I could check on this computer for the time and date listed on this bill, and saw nothing showing that time or date, nor site.

I feel as though a company is attempting to take advantage of me by sending me a fraudulant bill for $31.06 for 13 minutes on a site I'm unaware of, and have no record of having ever accessed. Most bills which are for websites usually show web addresses, which this bill shows nothing to that effect. I'm sure there is something that can be done about this. If so, what may be done??
