Not allowing FB payments

Ive been struggling to use my Capitec Bank card to pay for my advertising on Facebook for weeks now. I sent a mail to the clientcare email. Recieved a response from Nonela Ndabula informing me that Facebook is a blacklisted merchant on their side. I advertise my business on Facebook. This is my main way of advertising. I rep**** asking if Capitec could remove this on my card as I WANT to pay Facebook. I have had no response for a week. Can someone please assist with this? YOU are my bank and I should be able to use my card and money for WHATEVER I please. My FB account has now been suspended and I am losing business.
