Chargeback dispute

I purchased a British airways ticket, Comair got liquidated. I read an article that stated how to get your refund back after the liquidation. It read that we must contact our banks and the matter shall be resolved. I contacted my bank 03/07/2022 and explained the matter and I got a form forwarded. I completed the form and sent it on the 04/09/2022, the bank went quiet thereafter, I started following up since 18/07/2022 and I spoke to an agent. She said that she logged the dispute and gave me a reference and a sms followed with a date which was 31/08/2022. I called on the 30/08/2022 to follow up on the progress of the chargeback, I was informed that the original dispute was incorrectly logged and the agent said he logged a new dispute and I should not mind the new date that I am getting as this was an old dispute it'll be handled with urgency. Now I have been calling ever since and getting one story about how they understand my frustration and yet there is not enough information about how far my chargeback is. I am so frustrated and I am very disappointed. Every time I call I get an agent and they always promise to call me back but nothing.
