Yes , we need more system of protection from such hacks . Happened to my account last year , and they took my payment . Somehow airbnb replace some of it maybe around 75% , I forgot . Well , still they need to improve their security system . And also we cannot communicate thru email , the only way is phone call to their office , you might need to wait like 10minutes for an answer, but afterwards they will handle your case . Just make efforts to place a call , and they will handle your case . I only wish there is a simpler way to communicate with airbnb . Thanks
