POOR SERVICE , CLIENTS ARE NOT PRIORITISED

I AM IN UTTER DISBELIEVE WITH HOW MOMEMTUM TREATS THEIR CLIENTS MY COMPANY SENT IN A CLAIM IN THE 8th AUGUST ALREADY TO MY SUPRISE THE PROCESS WAS TAKING LONGER THAN USUAL SO I CONTACTED MOMENTUM ONLY TO BE TOLD NO IT TAKES 26 FOR A CLAIM TO BE PROCESSED. ITS EXACTLY A MONTH OF WAITING TODAY AND THEY TELLING ME THEY HAVE NOT RECEIVED MY CLAIM WHEN I HAVE JUST SENT THEM PROVE THAT IT WAS SENT , NOW SUDDENLY THEY ARE SAYING THEY DID NOT SEE THE EMAIL I MUST WAIT ANOTHER 26 DAYS ,SHERRY HARWOOD PROMISED THAT A MANAGER WHOM I HELD A PHONE FOR OVER 30 MINS WILL CALL ME BACK STILL WAITING FOR THE CALL I NEED TO SPEAK TO SOMEONE SENIOR URGENTLY THIS IS SO WRONG ON SO MANY LEVELS
