Long story short: I signed up for pest control service today and watched the dude basically do nothing for the initial service except spray around in a few spots outside my house. I'm pretty sure I got scammed. Is it too late to get out of this contract without paying the early termination fee now that he's "performed the initial service"? Since I signed the contract today, I'm still within the 3 business days and the wording of this confuses me:

​
