Pathetic FNB Credit Card Customer Care Service!

I currently reside overseas and wanted to make a credit card payment for services using my Virtual Credit Card (VCC). The facility failed on numerous occassions despite me adjusting my daily limits. I laid a customer complaint via the app on 5 May 2022 and received an email with a complaint reference number saying a consultant will contact me in 24-48 hours. Nobody contacted me. Again, on 11 May 2022, I laid another complaint via the banking app. I received the same email message as in the aforementioned. Guess what? Nobody has contacted me again, and today is 16 May 2022. How can a company that claims to have exceptional awards and services not get the basics right? I have a simple problem that cannot be resolved. Nobody bothers to contact me at all. Shame on you FNB. You take my money everymonth, my investments, my loans, etc but you don't have the courteousy of resolving my urgent problem? I am paying you a credit card service fee every month. To receive terrible service like this?
