I contacted McCann for information but decided to go to a different college. They continue to email, text and call me despite me repeatedly asking to be removed from their lists. I have had to block their numbers and email addresses to end the harassment. Eventually, they will run out of numbers to call and text me on, I hope. Just know that if you ask them for information, you are basically signing up to be contacted relentlessly, forever.
