Help Please regard Columbia House free DVD offer posted awhile back

[Huggies]

There was a link posted for a free no obligation DVD from columbia house i believe there was a short survey that was required to be filled out before they agreed to send the free disc... Well columbia house decided to mail me another disc and charge my mastercard without my permission and I need to find the link where the free no obligation DVD offer was and I didn't see anything in history as it has been awhile so please LMK i would appreciate it!
