Mail for me hasn't been delivered.

I have moved some times in the last a year so I've applied for the post office to forward mail, and mail for me had been forwarded correctly.

Since about a month ago, no forwarding mail comes. I had been feeling it a bit strange, but I didn't care about that so much.

But I found that the last months' cell phone bill hasn't come. I asked the cell phone company and they said they have already sent it to me and it hasn't been returned. Finally I was sure that the mail forwarding wasn't working.

I went to the post office.
They checked it (they kept me waiting long time.) but nothing was unclear.

Probably, some mails for me were lost before I receive. Too bad!
I hope there isn't any important mail among them.
