You could ask them for a block on International calling. That wouldn't stop the abuse necessarily, but would stop the calls to Mexico.
Any chance you have a cordless phone? That's the first place I'd look if I had a bunch of calls turn up on my account. Obviously, you'd expect to pick up the phone and hear someone using your line, but unless you've got teenagers, your home phone probably isn't in use that often.
