How to stop love calls!?

It's a long story, so if you aren't ready to read then press 'back'.

Okay well...one of my friends from one of my classes asked for my MySpace password. I figured I could trust her. Now, I'm getting calls from someone in a class who I feel extremely uncomfortable with. She called me about half an hour ago and said the words "I love (the annoying person" were on my MySpace. I checked, and it was not there.

Now our phone is constantly ringing (there it goes now) and giving me love notes about dating. I HATE it! It's so annoying! How can I stop it from happeni (There it goes again)! I don't want her to know my number! But she'll call until the day I die! Please, give me any help you can. Please. It's wakin up the dogs and I'm embarrassed for ANYONE to know. She's also asking questions I rather don't feel like answering.
