What can I do if DWP sending important documents but they still haven’t arrived?

Hi
I am currently doing my PIP review and had asked the PIP helpline on the 4th November, if they could send my last PIP form (and additional pages) from 2021, as I had been very stressed when I did it and didn’t have any help to do it at the time as it was during Covid, so I totally forgot to take a copy.

I rang to ensure that it had been sent last Friday as I was starting to panic as my deadline is getting nearer and I really need it to refer back to what has changed (a lot!) and they told me that it had been sent on the 6th and could take up to 7-10 working days.

Today is the 10th day and I still have not received it! I’m going to phone them again but what should I say? Is there anyway to get them to email it? Or send it again but first class next day type thing? I’ll even offer to pay for it, I’m that desperate, as I’ve already had a few extensions!
Or send it to a job centre or the council for my father to pick up?

Basically is there anything I can do? I just want to get this over with, as again I have no help and on top of that, I’ve just received the letter asking me to transfer to universal credit (sent on the 14th but got here yesterday!). I’m extremely stressed and don’t know what to do. I’m also having major problems getting any support letters…my psychiatrist said she would write one on the 18th October but despite politely chasing, I still haven’t had that either.

Should I try to contact Royal Mail or the local post depot to see if they could track it down?

Any advice would be greatly appreciated!
Thank you.

Hi BIS

Thanks. I phoned them in the end after a lot of encouragement and got through to a case worker eventually.
As usual there had been some confusion (they lost my mandatory reconsideration twice one year), and apparently it doesn’t seem like it had been sent till the 14th (when I phoned last!) rather than the 6th. The guy I spoke to was very helpful and took my email address and is going to speak to the records team to see if they could email it but said to ring again at the end of next week if it still hasn’t arrived, either way.

He also gave me another extension (I hope…I always doubt myself until I have proof and I won’t get the text confirmation till tomorrow!) till the 15th January, without me even asking! He just did it and let me know at the end of the call. I want to get it done way before then, because it’s so stressful but at least I don’t have to rush as much and I’m sure I’ll be asking more questions here, as I go along, as it’s the first time I’ve done a review, despite claiming for years (always won at tribunal before) so it’s all new to me.
