MORKELS REFUSES TO ME ME A PAID UP & CLOSE LETTER

THIS IS WORST CUSTOMER SERVICE I HAVE RECEIVED IN MY LIFE. I AM STILL WAITING FOR THE MORKELS PAID UP LETTER FOR THE ACCOUNT THAT WAS SETTLED EARLY LAST YEAR. I NEED THIS PAID UP LETTER TO GET A CLEARANCE CERTIFICATE, SO THAT I CAN HAVE THE DEBT REVIEW FLAG TO BE REMOVED ON MY NAME. DO I NEED TO BRIBE SOMEONE TO GET A PAID UP LETTER OR PAY FOR IT?????WHY DON'T YOU AT LEAST COME BACK TO ME???
