Shocking after sale service

I booked a flight with flight center, my flight date got moved and I could no longer make that particular date. I requested a refund from flight center which was on the 7th of April 2021, I initially got told by Mpho Sithole that it would take 6 weeks, then it got changed to 6 - 12 weeks and now I have just been informed that I need to wait another 4 weeks. The shocking is absolutely DISGUSTING. It took me 3 minutes to book a flight and for them to take my money but they expect me to wait 16 weeks to pay it back. Do not support Flight center, absolutely non existent after sale support.
