APPALLING IPID

I DO NOT KNOW WHAT IS THE PURPOSE OF IPID WHEN YOU CAN NOT EVEN TALK TO ANYONE ON THE PHONE DUE TO THEIR EXTREMELY TERRIBLE PHONE LINE WHICH SOUNDS LIKE HELL. THEY GAVE ME ANOTHER CONTACT NUMBER TO CALL WHEN I ASKED THEM IF THEY COULD HELP WITH A COMPLAINT I HAVE ABOUT A POLICE OFFICER. THEY TOLD I HAVE TO CALL A CERTAIN NUMBER. I TRIED TO DIAL THE NUMBER THEY GAVE ME BUT IT IS ALSO USELESS BECAUSE NO ONE ANSWERED. THIS IS IPID CONTACT NUMBER THAT SOUNDS LIKE HELL WHEN YOU DIAL [011 220 1500] AND THE ONE I WAS GIVEN IS [011 274 7786] BY IPID
