I was under Debt review until recently

I was under Debt review until recently. I received an SMS saying if I settled my PL they would offer me a discount of 45% which they did and I Paid that amount. In the same call I thought I'd see if any other offers were available for discount to settle my CC as well as OD facilities. The answer was no and I'd have to settle those amounts in full. Which I did. The settlement letters were sent and I made the payments in full for both the OD and the CC. The very next day I get an SMS from Absa again saying if I settle my credit card they'll offer me 45% discount. Literally 24 hours after I had already paid it up in FULL. This was a substantial amount of money and I called in to see if something could be done but they have no interest in helping and tell me they can't do anything because the credit card has been closed. Yet the account still shows as open on my banking app and they transferred paid up funds into it today? Very classy Absa.
