Returning Delay

I'm so fed up.
Two weeks ago, my brother finally sent me my "very important document" with registered mail which I told him to mail it with express. He explained that it was because he didn't bring enough money at the time. But it only took 7-10 days.
Fine. Yesterday, exactly 7th day, I asked my landlord about my letter. She told me that there was a mail that required to sign in the morning. But she didn't sign it because she didn't know it was mine.
"It said L-O-O something..."
Great. You knew my name is Loo. Let me remind you that 2 weeks ago, I told you that there will be a mail for me from M'sia.
"Oh don't worry, they usually will try to send the second time."
I couldn't sleep the whole night. The next day, I woke up at 8:30am, which is a big sacrifice for me because I am never a morning person. I called the Canada Post and I got a very disappointing answer.
However, I wasn't about to give up. I went to Bayview Village and the lady told me that I need to go to the one on Yonge and Sheppard for parcels and letters pick-ups.
So I went there. I saw a postman walking pass and without any thoughts, I ran up to him. I didn't care. I was very desparate.
I realized one thing, people seem very willingly to help if they see you are in a very desparate position.
The postman was very helpful and he gave me a phone number to call. Without delaying any minutes, I quickly called the number.
Again, people seem very willingly to help if they see you are in a very desparate position.
She patiently help me to look for any details about the mail as possible. There was a hope running in my head.
"I'm sorry, the mail had been stamped "NOID" and it is already on the way sending it back to the sender."
I could clearly hear the breaking sound of hope on the floor.
"Do you know how long it's gonna be to sending back to the sender?"
"I don't know. Once it leaves the country, we have no idea how long it's gonna take."
I was so upset.
Sitting on the train, I felt like crying out loud.
Canada Post is used to be very slow motion. Why did they act so fast this time? Shouldn't they just keep any rejecting mails for few days in case the right receivers come and claim it? UPS does that but why not Canada Post?
Could I blame it to my landlord? my brother? or Canada Post?
Maybe I should have told my landlord clearly about the mail. I shouldn't have assumed that my landlord was smart enough for that in the first place.
I have no choice now but wait.
I pray that it wouldn't take long to come back to my side. I'm not willing to delay my flight and put all of my plans on hold because of this stupid incident. Please!!
