STILL WAITING FOR REQUEST TO BE ATTENDED TO

WHEN WILL I GET THE LETTER I REQUESTED ON 21 JUNE 2015. SINCE LOGGING COMPLIANT ON THIS SITE, I RECEIVED AN E-MAIL APOLOGISING FOR THE INCONVENIENCE, BUT I HAVE STILL NOT HAD A RESOLUTION. I HAVE HAD TO CALL INTO THE CALL CENTRE COUNTLESS TIMES AND STILL NO LETTER. ALL STAFF CAN TELL ME IS THAT MY QUERY IS OPEN???? YESTERDAY WHEN I CALLED IN I RECEIVED A NEW REFFERENCE NUMBER (774715). HOW DIFFICULT IS IT TO TYPE A LETTER AND SEND TO YOUR CLIENT???. I HAVE CALLED YOUR CALL CENTRE AGAIN TODAY, AND CALLS ARE NOT BEEN ANSWERED.
