THEY CLAIM TO CARE ABOUT THEIR CUSTOMERS BUT CLEARLY THEY DONT’T

I sent a Debit Card dispute form the week before last and received a confirmation email saying that they would get back to me within 5 working days. Those days passed. Then I sent another dispute form and got a confirmation saying they would respond in 2 working days. Those days passed. Then I sent a query online asking what to do next and got a confirmation saying they would respond in 24-48 hrs. Those hours passed. Then I sent an email to their customer care email address. NO CONFIRMATION OF RECIPT. I am not in the country and I desperately need this issue resolved soon and it feels like FNB has completely dismissed me.
