Software Pros I downloaded Avast supposedly for free and I was asked for my cc and I got a $99 charge to my bank account. Internet

I downloaded a free copy of Avast a antivirus and in other to do so I had to provide my debit card information and a day later I noticed a charge in my bank account for $99.94.  I sent a note to billing support disputing tha charg and requesting a refund and this what I got.

Dear Freud,

We apologize if you misunderstood the website billing, but you were properly charged.  Your billing details are listed below.

50.96 for the 3-year membership.  It is 16.99/year, but as stated on the site it is billed as a one time fee.

19.08 for the download accelerator.  This package gives you the fastest download speeds possible for the length of your membership.

29.94 for the download protection which gives you access to any new releases or updated versions that come out during your membership at no additional cost.

We hope this clarifies the membership fee you selected.  If you need changes made to your selections or any further assistance with your account please reply to this email.

Thank you,
Software Pros Support
