Review NOT ANSWERING CALLS

FOR HOW MANY YEARS DO WE HAVE TO CALL & CALL ON THE PHONE UNTIL THE STAFF WOULD ANSWER US???...
ALMOST 20 TIMES IN A DAY I CALLED BUT NOBODY ANSWER EVEN ONCE?
WHAT'S THE USE FOR POSTING YOUR PHONE NUMBER IT JUST KEEPS ON RINGING BUT NOBODY ANSWERS??? that was terrible!!!!
