This blog post contains total non information. So please, move on if you have better things to do. I warned you.Seeing is believing! Yes indeed! After I had - for the fourth time in four months - a problem with my invoice, I called my mobile provider, know as Proximus in order to have the error corrected. Alas, I never got through to them. I gave up after 1 hours and 5 minutes of listening to their promo music.
On the other hand, if you are bothered with the service level offered by the help desk of your mobile provider, have a look at this picture from my Android phone and know that you are not alone.
