Received decision but pathetic 2 tra award

Hi Gordon
Just an update so after waiting 7 1/2 months for my DLA to PIP decision I could wait no more so today I called DWP as nothing in the post today.
A very nice gentleman adviced me a decision had been made on March 1st and letter sent out
I asked if he could tell me over the phone which he said he would so with baited breath I listened.
I've been awarded Enhanced Care he said but no mobility I said are you sure now crying !!
My medical report I have awarded me 12 points for mobility so how can that be ?
He looked again and said yes you have been awarded 12 points there must be a mistake he said.
Went away and checked came back and said we as in DWP have issued you an incorrect decision letter you have been awarded Enharnced for both and I will get an amended letter ignore the one which will arrive anyday now.
Then asked how long the award for ..... 2 years he said to which I burst into tears again!!
So previously a life award for DLA but now a pathetic 2 year award which took them over 7 months to make !!!
I am awaiting the decision maker calling me back .........
Where do I stand with regards to a MR ?
Can I ask for a MR based on the award length ? Or is this not allowed ?
Or do I shut up and except this pathetic decision?
I've been ill since I was 3 I'm now 47 so in 44 years I've seen no improvement and won't so how on earth can I be given such a short award.
I will tomorrow call the decision maker if she/he doesn't call me but could you advise what do I say or give me a few pointers please.
The award is from 21st March so technically March 2019 I'm going be asked for a review .
Please advice before I throw myself under a train !!!
As always thanks for your advice

Thanks for your reply tomorrow when I call I can all but discuss it and see what he/she says.
My argument being that I will not improve so how can I have such a short award also that the comments mentioned in my assessment report I feel are not accurate.
Surely a condition which won't improve but remain on a gradual decline merits a longer award ?
Also would I be in my right to complain about the time taken 30 weeks !!
Any advice appreciated

Thank you Gordon
I will see how th DM comes across I take on board the fact they can take as long as they want
But I will point outwithout rocking the boat as such that 7 1/2 months to make a decision has caused me considerable distress and to only be given 2 yrs and also the fact that even then they can't even send out the right decision.
Can you imagine if I hadn't called today and tomorrow the envelope arrives someone with severe mental issues might have reacted very differently to how I would / did !!

I too got 2 years after having an indefinite DLA award. I have several letters from hospital consultants saying my condition is permanent & it has been since 1990.

After all the stress and worry of changing to PIP, I decided to take what I had been given, rather than risk losing everything. Like investments, if you appeal, your aaard can go down as well as up. It leaves a bitter taste in the mouth, but personally if you’ve been successful in getting PIP, I’d swallow the pill and keep quiet.
