OneClickCash.com unknown Tap into my account Internet

i apply for a loan with a company on the inter net and signed their contract on line. the money was put in my bank account as agreed. i signed their contract only. oneclickcash kept popping up om my yahoo site and i declined. then weeks later i was checking my bank account on line and seen that oneclickcash had withdrawn $75.00 out of my account. 

i reported it to my bank who gave me oneclickcash phone number. i called 18002303266 and spoke to woman name Annette who told me that they gave me a loan for $250.00 and that I still owe them $320.00 more dollars. 

i told them that i never sign any contract from them and that they had to get the information from the only loan service that i apply for. Annette then told me that i did apply for them, but that i can call their complaint office and dispute this.

the information given to me from this person was incorrect. she told me that they do not have a address and can not mail me any information showing that i apply or signed a contract with them, she told me that i can fax my dispute to this fax number, which is also incorrect 18004916913.

i did not apply for this loan and i do not know anything about them. please help me get back my money and not have to pay this company who rip me off and states that they will continue to take from my bank account.
