You must wait 45 days for Capitec to Close your Credit Card after settling the account!!!!!!

It's an absolutely ridiculous and unfair business practice to pay off a credit card and then be forced to wait 45 more days for the account to be closed.. I've never heard anything like that in my life - I paid all the outstanding fees and there are no funds outstanding from my side, why must I wait? Why is Capitec refusing to close off the credit card? Is this a tactic used to entice the client to use the credit card again?
