PC Tools Auto Renewal BOGUS charge to my bank account, Internet

We recently discovered a "renewal" charge of $29.99 to our bank account on-line.  The charge was from PC Tools.  A company we have never heard of offering a product we have never ordered or used.
Trying to contact them directly is a JOKE.  No customer support link, no phone number, no way to contact directly.
No idea how they gained access to our account (like so many others who shop on-line I suppose).
Any information on how to contact them directly and deal with an English speaking human being would be very much appreciated.
