Registration of Capitec debit card for online shop

I have requested a few weeks ago that my debit card be fixed so that I can use it for payment of my google adwords account. I use this for business advertising and every day that goes past I lose business. My previous card worked perfectly. I got a new card because I Iost the old one. The new card has been succesfully registered on Capitec s website for internet banking. After the fourth attempt though. For some reason mastercard does not approve my Capitec Card for the payment of my adwords account. All my other online shopping works fine. This is the second time I am complaining about this on Hello Peter. In the meantime I am losing prospective clients!
