ACTIVE [dot] COM contracts

Hi all! I needed a bit of feed back. I hosted a fun run for my friend last year to raise money for his wife’s medical bills after being diagnosed with a terminal cancer. I ended up using Active.com because I didn’t know that there was anything else out there to use. My friend’s wife died a few days before the event and we weren’t sure that it would be a yearly thing. So this year we decided to go ahead and do it again and ACTIVE.com is threatening to sue me because I apparently signed a “contract” for 3 YEARS to be exclusive with them. They sent over said “contract” but it doesn’t have my signature on it, nor does it have my name on it, only the event name. How can I get out of using ACTIVE.com? They are bullying me now into using them, esp after they found out that I am using Race Reach- which has been a million times better (and less expensive) than ACTIVE could ever be and I don’t want to use any other company now. Has anyone had a similar issue with ACTIVE? I’m an individual and not a company or an organization so I don’t know what to do. I want to keep this going as a legacy to my friend but being bullied by a company (when they might make $500 off of my event) is very stressful and I do not want to give in to them. Thank you in advance for your input!
