PeopleSmarrt recurring charges Internet

In August 2014 I paid for a background check on an individual using PeopleSmart website.  I did not see on the site where I would be charged a recurring charge.  I was under the impression that this charge was a one time charge.  I used my mother credit card because the individual she had hired wanted to rent her apartment.  I told not to committ to renting to this individual until we got a background check.  She never noticed the charge on her account until she had closed the credit card and the credit card agency sent her a notice that this company PeopleSmart was submitting payment for monthly charges.  I contacted the company and spoke with someone about the above circumstances and wanted to be credit for the charges from September through this month.  They sent and email stating that the account was closed today but that we had several thousand credit to use on their account.  I don't need to make background check for this amount of credit.  I wanted a refund for the months that we were not aware we were being billed for.
