Harassed by missed and dead calls

Mondo's call centre has an automated dialler, which regularly ends with missed calls or dead (nobody on the other side). These dead/missed calls from them are extremely irritating, and I consider them harassment, especially since I didn't sign up for them.<br> <br> Is there a legal course of action to take against them, similar to the cases in the last few years over dead/missed calls from automated dialers in the UK?
