I also got a bill from my phone company for WEB ACCESS 1.0 minute. Billed $37.28 from MCI. I found out from AT&T this was a charge from my computer and I have no idea how it was done. Also found out that even if you block 900 calls on your phone it does not apply to the internet. I asked to speak to a supervisor with MCI and she said she would remove it from my bill within 7-10 days.
I put a complaint with the Federal Trade Commission- 1 (877) 382-4357.
Also with the Internet Crime Complaint Center (IC3)
