MY OUTSTANDING REFUND

I WROTE A REPORT HERE LAST WEEK OR SO ABOUT MY OUTSTANDING REFUND FROM ADT. THEY THEN CALLED ME TO SAY PAPERWORK FOR IT HAS BEEN DONE. UP UNTIL TODAY I AM STILL WAITING FOR MY REFUND. I CALLED THE ACCOUNT DEPARTMENT ABOUT 30MIN AGO, SPOKE TO THE CALL CENTRE AGENT BY THE NAME OF AYANDA, WHO TOLD ME THERE WAS NOTHING ON THE SYSTEM ABOUT MY REFUND. ASKED ME TO EXPLAIN WHY AND HOW MUCH WAS I SUPPOSED TO BE REFUNDED. I WAS THEN PUT ON HOLD FOR 20MIN. I LOGGED THE CALL ABOUT THE ISSUE ON 03/02/2015. THEY INFORMED ME IT WILL TAKE 21 DAYS TO REFUND ME MY MONEY. 21 DAYS HAS PASSED, NO REFUND HAS BEEN MADE. TAKING INTO CONSIDERATION THAT ADT BILLED MY ACCOUNT THIS FEB FOR MARCH ON THE ACCOUNT THAT WAS DISCONTINUED. I AM LIVID. SERVICE PROVIDERS LIKE THESE BELIEVE IT IS OK TO BILL AND BILL THE CLIENTS AND LATER REFUSE TO REFUND THEM WHAT IS DUE TO THE CLIENTS. I WANT MY MONEY ELSE I AM EVEN GOING TO CANCEL THE DEBIT ORDER FOR THE ALARM ON THE NEW RESIDENTS. WHERE DO THEY THINK ONE HAS THE MONEY TO PAY DOUBLE INSTALMENTS. WORSE ADT BILLED ME FOR THE RADIO ON THE NEW HOUSE OF WHICH THE CONNECTIONS WERE ALREADY THERE. ALL THEY NEEDED TO DO WAS TO MOVE MY ALARM FROM ONE RESIDENT TO THE OTHER.
