Complaint against AirPeace Airline

I bought a return Airticket from JHB to Nigeria.Travelled on the 20th Feb 2022 .On my return 02 March 2022,to my surprise there was no flight,without any notifications from the Airline.Became stranded,frustrated at the airport, had to get an emergency accommodation which I had to stay for 2days whilst trying to get another flight back to SA.The next day I sent emails to the offices of AirPeace,they claim to have tried to contact me .By the way I had all the relevant international accesses on my phone and yet not even a single call or message.I had to buy a ticket from SAA which cost me another R7778,90.They subsequently refunded their own ticket R4102 only but disregards my plea for a refund of the SAA ticket which resulted from their incompetence in dealing with customers.Bearing in mind that I am not even asking for Accommodation,meals,Retest of Covid bills.All that I am asking is the SAA ticket refund. Even now after sending numerous emails .They continue to say they are forwarding my complaints to their appropriate department.
