Blocked card

I've been a loyal Foschini account member since the year 2000. I had financial problems during the mont of June/July which I fully paid my account. Foschini kept sending me statements with accumulated interest with no purchase. I decided to close the account to purchase when I'm ready, today I decided to make a purchase and their customer consultant blocked my card due to me not remembering my 2000 employer who ask someone about their 2000 employer in 2021? Therefore I could not purchase I'm told to bring 3 months bank statement really??? Foschini has zero customer service people should stop supporting the group treating customers like *****s.
