IC *Freeshipping.com IC *Freeshipping.com somehow gained access to my bank account and a credit card account and made charges of $12.97 Wethersfield Internet - CT

My wife had a phone conversation with an employee of "IC *Freeshipping.com" named Candace (Phone No.: 1 (800) 515-9185) on October 2, 2017, wherein my wife had enquired about the charge of $12.97 appearing on a statement for my Sears Credit Card. My wife had advised Candace that one order was made last July via Kmart using my Sears Credit Card; that shipping was free as we met the requirement of spending over a certain dollar amount; and that we did not sign up for any membership with IC *Freeshipping.com. Candace said she would not remove the first charge of $12.97, would not inform us what the "IC" (Insider Club) stood for nor would she provide us with an email (Customer Service@freeshipping.com)/physical address to its Headquarters. Candace alleged that we had signed up with the company she represents. My wife asked her how was it done. Candace' s response was that Emails were sent to both of our email addresses "in September". We have searched through our emails and found no such evidence. Had we even received such emails, it does not constitute an agreement between both parties. This Company also gained access to our bank account and charged $12.97. Charles Tracy, California
