I have no idea how these people initially got my contact information as I never applied to the school in the first place. I went through my phone log, and they've called me 21 different times in one week, usually they start calling around 8am...which is just lovely. They never leave voicemails, but the one time they did, the woman on the phone was an absolute snot. Their constant phone calls make me want nothing to do with the school, especially since it seems credits don't transfer well. I've already told a few people to please stop contacting me, but obviously that didn't work...so maybe they'll read this? I've never felt so annoyed by college before.
