Complaint Review: USA Voicemail

A charge of $19.95 excluding tax, was placed on my Alltel personal phone bill for Voicemail services.
I had not requested this service.
I contacted Alltel and they removed the charge and provided my with phone numbers to contact USA Voicemail directly.
The first number given was 1.800.354.9888, which I was placed on hold for 20 minutes, was the phone number for billing company for USA Voicemail. I was given another number for USA Voicemail itself.
That number, 1.877.439.3802 was answered within 10 minutes and the representative responded politely and efficiently, acknowledging the incorrect placement of a charge which I had not ordered.
It appeared that this charge was initiated by a Pop-Up window on my computer.
