Affinion Benifits Group Cuna Mutual, BCI Direct withdrawl out of my account for a insurance policy that they cannot provide proof exists Franklin, Tennessee

Money has been being deducted from my account at a local credit union, when I asked about the withdrawl they indicated it was for Cuna Mutual Insurance. When I contacted Cuna and asked for a copy of the signed enrollment form I was told to contact Affinion Group as they were the original company contracted. Affinion has refused to provide a copy of a signed enrollment form with my signature. I have no knowledge of ever signing one and have asked repeatedly to no avail. Not one company can produce one, not the Credit Union, not Cuna Mutual and not Affinion yet they have my money. I will also be filing a complaint with the NY State Insurance fraud division.
