NOT GETTING ASSISTANCE WHEN WANTING TO INCREASE MY HOME LOAN

I CALLED YOUR ***AND SPOKE TO LULU WHO GAVE ME A REFERENCE NUMBER ********** . PLEASE NOTE I EXITED DEBT REVIEW IN NOV 2017 AND I HAVE EMAILED ALL THE PROOF OF CLEARANCE INCLUDING THE FORM 19 - WHEREBY THE DEBT REVIEW LISTING HAS BEEN REMOVED, I AM EVEN PREPARED TO SEND ALL MY CREDIT REPORTS THROUGH SO YOU CAN SEE I DO NOT HAVE ANY DEBT AND I AM DEBT CLEAR. I would like to increase my bond By R75 000.00 as I need to urgently do renovations on my apartment that my tenants destroyed. I DON MIND PAYING AND I CAN AFFORD IT. WHY IS STANDARD BANK DENYING ME THE INCREASE??? I EMAILED NUMEROUS TIMES AND NO ONE IS GETTING BACK TO ME. WHAT IS HAPPENING?? MUST I RATHER GO TO ANOTHER BANK OR MOVE MY HOME LOAN TO ANOTHER FINANCE INSTITUTION???
