National Platinum Member Services USA unauthorized withdrawal from my bank account without my knowledge Charlotte, North Carolina

I was browsing the internet for potential possible short term loan. I was told my bank information was required to determine eligibility. I never e-signed a contract nor agreed to any loan. I was only gathering information. I was never contacted by anyone via phone, e-mail or fax.

Two weeks later I dicovered my checking account had $99.95 withdrawn from it without my knowledge or authorization by this company. I cannot reach them by phone. Their hours are 9-5 est while I'm at work and they don't have weekend hours.

How can someone do this without a signed contract or authorization, either written or verbal?
