The MBS billing affair that's affected thousands of PC users and has become one of the most talked-about issues on the PC Advisor forums has been picked up by BBC Radio 4's Your and Yours programme. PC Advisor's very own Forum Editor, Peter Thomas, was called in to provide expert analysis on the issue.

If you've been caught up in this, or are simply interested in the tactics used by MBS to charge web users – go to the You and Yours website and listen to the show from Friday 6th July.

As we reported here, we've been inundated with complaints from outraged readers about MBS' billing practices, but as far as we've seen so far no laws have been broken.

You and Yours spoke to both the Office of Fair Trading and Trading Standards, and said MBS's owner plans to amend the Terms & Conditions of the system.
