I too, am a victim of the montsr.com ripoff.
I contacted the 800-897-8063 number, and finally did speak to a service person, who informed me that, in thier business, which deals in many things, including adult sites, there are unscrupulous persons out there, stealing identities, and using thier name and card #s.
I have been tagged with two charges of 39.99 one in Jan and one in Feb. I cancelled my card, and an investigation by my bank is underway.
Rep from montsr.com said the charges were generated in my name, using my card, but from a location at Ithaca College. (??)
As I have a dispute filed with my financial institution, montsr.com asked that they contact them, and I will be reimbursed for the charges, according to them.
Somewhere out there our card numbers and names have been intercepted.
