Platform 9 and 3/4?

Where does all our missing post go to? I've often wondered this, you clearly address a letter, you stick on the correct stamp - but voila it's gone!

The reason why I ask this is, that so far it has taken since Feb 5th for a letter to get to it's destination and be acknowledged that it has arrived.
I had an interview at my local job centre plus on Feb 4th, and was told by my advisor that I should have been placed in the ESA support group, and NOT the ESA WRAG group. My advisor gave me a self addressed envelope and told me to send a letter off explaining about my illness and that I would like them to look at their decision again. The envelope was addressed to somewhere in Bradford, when I queried this my job centre advisor informed me that Newcastle was snowed under, so they sometimes send things on to be assessed by other offices in other areas.

I duly sent it off the very next day, luckily remembering to take a copy at the last minute.
Time goes on....... 3 weeks in fact, hmmm I hear nothing.
I decide to find out what's going on, I look for a phone number/contact number for my local job centre - can't find one, just an 0800 central number (expensive when your mobile contract doesn't include these numbers).

Dimwit 1 answers phone, I explain my situation.
Dimwit 1: You are not in our system, therefore your letter must have been lost, can you resend it? It shouldn't have been sent to Bradford, it should have been sent to Stockton.
I ask to be put through to my local job centre,  Dimwit 2 answers phone - again I explain situation.
Dimwit 2: Your letter shouldn't have been sent to Bradford or Stockton, it should have been sent to Gateshead. Now I'm really confused!
Next I ask to be put through to my job centre advisor who gave me the self addressed envelope in the first place. He says my letter did indeed go to the right place, but must have got lost, and that dimwit 1 and dimwit 2 don't know what they are talking about.

So..... I resend letter to Gateshead (well, best out of 3). A few days later I get a voicemail from dimwit 3 who says: We have received a letter from you that has come to the wrong place, we will pass it on to (who knows where) I stopped listening at this point, actually that's a lie, I was in fact swearing so loudly the message and in fact everything going on around me for a 2 mile radius could not be heard over the shouty, sweary words coming out of my mouth!

And so darklings, it is now the 16th March and after almost 6 weeks I am none the wiser. I do believe that Platform 9 and 3/4 exists and all our unreceived post goes there - on the other hand I probably really believe that our country is run by dimwits!
