No international transfers into Discovery Visa card

I have been using Discovery Visa card for a few years. Upon receiving an SMS to pay my balance, I have transferred $2000 from an oversees account as I have been doing for many years. However, after not getting my money for 8 days, I have tried to contact the bank through a function “call me back” on Discovery app, for at least five times. Nobody has bothered to call me back. I have called them directly but unfortunately their system is not working properly. The managers don’t have a direct line, call center could not help, blaming their system. In the end I was told by one of the managers that Discovery no longer accept transfers from oversees since they still did not receive their license. Since I transferred the funds to my usual Discovery card not knowing that the card has been transferred to Discovery bank from First Rand bank, my money is now missing, somewhere between the two banks. My card still states Visa and was never changed to Discovery Bank card. A few months ago, when I spoke to Discovery consultant, I was told that it is not mandatory to move to Discovery bank. A month ago, I did ask one of their consultants to call me back to discuss this issue but nobody did. Not in any of their communications I was advised that Discovery bank can’t accept transactions from oversees, like it used to be in the past.
