*****, don't open Makro cards

Makro cards and credit cards not safe, no security. Makro credit card safely in my possession, have not used it for more than a year ago, was being used. I stay in Cape Town, Brackenfell. Purchase made in Johannesburg of R19 000 at Incredible connection. It has been month now, all they do is apologize, but still send me sms en email for me to pay the account, simply ***** case. Why can't no one correct this mistake, what would be my next steps now?
