Dan Cain got way more mail than he bargained for. Cain told WOIO he was sent more than 55,000 copies of the exact same letter from his daughter's student loan company. He knew something was up when the post office told him, "You've got too much mail to walk through the front door," he told the station. Even worse, all of the letters had calculated the incorrect amount of interest, he said. The company apologized for the glitch and promised to send another statement. Hopefully, just one this time.'
