Old Mutual Money account card suspended with no explanation

My card got suspended for no apparent reason. I received a vaguely-worded SMS in the middle of the night notifying me of this. I have been in contact with two of their support staff, a Nwabisa Mazimela who insists that I go to my nearest branch to have the card reactivated. I told her multiple times that I am unable to because I travel via e-hailing services and they are linked to my card-so I would not be able to pay because the card is suspended. I asked her to escalate this or forward it to a person who would be able to assist remotely (of course she did not and made promise to). I also spoke to another unidentified employee who said they will get back to me after 8 hours (this was already after 12 hours of the card being suspended). Nobody has offered an explanation of why the card is suspended to begin with. I am now stranded because I cannot swipe my card, I cannot make online purchases etc. Their support agents have zero care and zero sense of urgency. This happened around 00:49, it is now 15:22 and the issue has still not been resolved. Definitely time to change banks.
