Poor communication which resulted in being stranded at the airport

My recent experience with Qatar airlines has left a rather bad taste in my mouth. On the 19/04/2022, my partner and I were supposed to fly from Istanbul to Doha (connecting flight), and then final destination Johannesburg, South Africa. At no point did we receive any communication to notify us of our flights been cancelled. Only after arriving at Sabiha Gocken International airport, I had realised that the flight had been cancelled when I had checked the airport’s international departures. Much to my surprise, there was absolutely no one that I could speak to at the check in desks or ticket sales that were present to assist. I had tried to speak to all information desks at the airport, with no resolve, and Turkish Ground Services were also not present to assist. This had caused my partner and I much destress and disappointment as we were then forced to break the bank in order to pay for more food, accommodation and transport. On 20/04/2022 I had attempted to speak to somebody at the airport regarding compensation for the additional costs that we were imposed on us, with no resolve as everyone just seems to pass on the responsibility to the next person. Being stranded in another country was not how we planned for our trip to end. Over and above all of this, it was impossible to get a hold of anyone to speak to from your support team. My expectations of Qatar Airlines were very much the opposite of what I had experienced, as you guys have also failed to respond to my communication to you.
