FORT MYERS, Fla. - Fort Myers resident Anna Suarez and her husband check their downtown P.O. Box every week. But Tuesday, they were in for a surprise.

"In the P.O. Box was a yellow note that said they had a package that was too big to fit in the box," said Suarez.

The package was actually a bag of mail with envelopes dating back to April 2011.

"I noticed I wasn't getting as much mail. What's the purpose of having a P.O. Box if we're not getting any mail? They were holding it," she said.

Suarez was getting some mail, "Like junk mail, most of the time, magazines, but never my important mail. My checks, the licenses, things from the bank," she said.

It took her half an hour to go through the pile.

"This is mail from more than a year ago and I've been coming here every week!" she said.

Suarez went back to the post office to find out what happened.    

"Somebody must know. They gave me the 1-800 number. I called and the lady said the same thing," she said.

Now she's losing sleep wondering if other important documents have been lost forever.   "It worries me yes, god knows what else. Last night i couldn't sleep thinking about it. It's scary, very scary," she said.

POSTAL SERVICE RESPONSE: We apologize for any inconvenience.  Several notices were left over an extended period of time, advising the customer that additional mail that could not fit in her PO Box was available for pick up at the counter.
