Business account opened with wrong surname

I recently opened a business account - an amazing service until I received with excitement my cheque card to find it is in THE WRONG NAME. The ID document I sent you specifically had my ****en name on it and the card issued is in my married name. I am divorced. In the long and involved process to kyc the business I sent you my divorce document showing the change in name. I am now trying to get this resolved - it is a mission. No-one seems to know how I do it, never mind how I ensure I get a new card with the right name and in future receive correspondence with my actual name on it.
