******** contract renewal

I wanted to cancel my contract with autopage a few months after i reached end of term. When i contacted them i somehow had renewed my contract. I did not even know about the renewal of my 24 month contract.<br> When i contact them by email asking to see my signed contract they just cant produce anything. They just keep telling me that ive still got anothe 18 months left of my contract before i can cancel. <br> I did not agree to any 24 month contract renewal and want it cancelled now....!!!!
