Your "make a difference" caused me the biggest humiliation

I app**** for a Woolworths store card in November 2019. I never received any feedback so on the 30th November 2019 I called and was advised it was approved and a card will be posted to me alternatively I can apply for a temp card. On the same day I went to Woolworths Adderley where I got the temp card and made my first purchase. I was left with available credit of R3000 something I went for another purchase on 7th December 2019 and was told that the purchase cannot be made as the account was closed on 3rd December 2019. It was so embarrassing and I had to pay for the items in cash which I was not budgeting to. There was explanation given and to date no one has contacted me to let me know what happened with the account. I was than called today by someone from finance instructing me to go Woolworths Adderley and pay the goods in cash that I purchased on the 30th November 2019 as I made purchase on an inactive account. After all the humiliation I experienced I don't think that is a fair request. I am not happy with the way Woolworths is dealing with this situation. Every person I spoke to cannot give me a reason why the account was closed without my knowledge. This is **** Woolworths, and I was starting to doubt my sanity because of this! For a company that promises to "make a difference"
