You don't need your receipt number to make an infopass appointment. All you need to enter is your Name, Zip and email address, if i remember correctly. And yes, there are links to cancel your appointment if you can't make it.
I made my appointment as soon as I received my email confirmation. I wasn't given the option of picking a particular day, it just gave me a day exactly 2 weeks from the day I made the appointment on. I could however pick either a morning or afternoon appointment.
