Failing to refund from Qatar airways!!

We are a family of four and were booked to fly from Johannesburg to the USA with Qatar airways on Saturday 27th of November 2021. We got email that same day in the morning that our flight was cancelled. Fair enough with concerns about omicron variant BUT for us to still be seeking assistance on getting our refunds for the trip is very cruel and insensitive of Qatar airways. Each time we reach out to Qatar airways we are referred back to Flight centre with whom we made online booking. An agent at Flight centre keeps promising to follow up with Qatar airways and get back to us. What I find very disturbing is how easy it is for Qatar airways to get money from us (booking took less than 5minutes) But now it is taking us almost a week to just get someone to start working on our refunds!!! The pandemic has been harsh to EVERYONE! We chose Qatar airways after recommendations from friends and I am so shocked with the treatment I am getting from them!! I am beginning to suspect we are now victims of Qatar airways' grand scheme of avoiding refunding us!
