Sorry to hear that Smoke. People just don't care and would never do the correct thing by leaving you a note at least saying sorry! Sadly time and again this apathetic display of disconnection to normal human interaction and common decency is here for us all to see.
How on earth Qatar will be successful in its future life seeing as so many of the locals and some of the expats continue behaving in this disgraceful manner is beyond me! It evokes a whole new topic I guess!
I hope you have no more nasty incidences like this that cost you time, money and heartache!
