Kostenlose grundlegende Tour, historische und kulturelle Tour durch Jaffa

I've been an avid Guruwalk fan for years, doing tours in many countries on all continents... This is the first time I got stood up by a guide. Despite confirmation and reminder email about the tour I booked, I waited at the meeting spot for 20 mins and the Guide did not show. He did not respond to messages either. Sure, things can get in the way, but he could have at least cancelled in advance. I find this incredibly rude and disrespectful.
