Please reverse the amount and cancel the card

I have two standard bank accounts, I then stopped one card which I nolonger use as I saw that there are still chargers of which my card was now having a balance of -R46,90.using my standard bank app I then stopped the card of which I nolonger want and I did not opt for a new card but the following day I received an sms stating I should collect my new card and when I check the statement it shows that I know have a balance of -R399.99 of which is for the new card and honouring amount that I do not know of and when I went to the branch they refused to help me and said I should pay the whole amount before they can close the account…I was willing to pay the R46,90 but now they telling me about the R399,99 of which I do not know because I did not request a new card as I have another active account
