Can the staff actually read?

I am battling to set up payment with discovery card. I have followed all the steps on the website and sent screen dumps with an explanation to discoverycard at discovery. co. za. It does not accept my 16 digit number on my card. keeps telling me it needs another number but that is the only number I have. The people replying to e-mails do not bother to read the mail. They just send you the same automated response that I have already downloaded and it does NOT work. Can they actually read, because if they did they would see I have done what they have told me to do. Why if you are just sending automated responses does it take 2 days to get a reply. yes, waited 2 days to get NO help. Have resent the mail, will take another 2 days to not get help again.
