Pathetic

I made a booking via Airbnb for next weekend that was cancelled without notifying me. This has put me in a serious predicament as my family are coming from all over South Africa to join us at the accommodation. The support I've received from Airbnb has been absolutely pathetic to say the least. The attitude of the person that I had to deal with on the support chat absolutely stinks!!!!! He/she refused to escalate my query to a manager and refused to confirm their details and the details of the manager. He/she then claimed that he/she is the manager of the department...!!!??? It is disgusting that you pay for accommodation on Airbnb and for them to just cancel the booking with no notification - and then to add to the frustration is to deal with an idiot that point blank refuses to assist. How do I phone Airbnb to discuss this matter with a person that is willing to assist???
