Bad service by TFG head office

I went to Foschini Cradock where the staff are always friendly and helpfull. I informed the consultant that i have midplaced my card and he informed me that they will replace my card. He contacted their HO to link the card and the person on the line had questions to ask, which i answered correctly but twice he informed me that i have answered wrong. When i asked him which of the questions did i answer wrong he could not tell me, one of the questions was whether i purchased a house at a certain address in PE and i told him that i've never lived in PE. My account is now blocked what tbe reason is i do not know. I had to submit a copy of my id and a three month bank statement. I want them to tell me which questions i've answered wrong and why my account is blocked. I feel that this consultant was very sarcastic and not helpful at all.
