Emotionally disappointing lack of service

Terrible terrible experience. Between booking.com and airline they have cancelled our CT to JHB leg to get from JHB to UK. Between airline and booking.com no accountability has been taken nor when the flight was cancelled were we even credited. We have 2 family weddings within days of one another. Regardless of policies as customer service one would expect thinking out of the box and simply doing a commercial gesture to book the cheapest leg they have cancelled as a gesture of goodwill which as an attorney we do daily in logistics. This is going to amount to 30k loss in travel fees paid
