ABSA - Not possible to reach by phone

I received a possible **** e-mail and have just tried to contact ABSA Credit Card Division, to no avail. The telephone number ABSA sends with SMS messages once one has done a transaction, being ***, does not work. I tried numerous other numbers listed by ABSA itself on the internet, to get hold of their Card division or at least another department, without success. The numbers listed by ABSA does not work! Even those listed on their website! In the end I had to call ABSA head office on a landline at ***, asked for Card division, and then had to enter my card number which I did. However I was informed by the electronic voice that my card number is incorrect! So I gave up, not being able to contact the largest bank in Africa telephonically. How is this possible? How can ABSA list various contact numbers that do not work? The levels of service of this bank is obviously following those of Nedbank, Capitec, Standard Bank and others - down the drain. What a disgrace for ABSA.
