BAD SERVICE

I CANCELED MY FIBER ON THE WEB, AND THEY STILL SOMEONE NEED TO CONTACT ME TO CONFIRM THE CANCELATION, I MISSED THE CALL, AND NOW WHEN I TRY TO PHONE BACK HOLING ON FOR MORE THAN HALF AN HOUR NO ONE IS PICKING UP THE CALL SO THE CANCELATION WILL NOT HAPPEN UNTIL I SPEAK TO SOMEONE IT BAD SERVICE
