I feel your pain
I did a PIP form a while back for my DS.
We were told on the phone the form would be with us within 2 weeks.
I called after 3 weeks of nothing (choosing options, waiting for 40 minutes) to finally be told it can take up to 6 weeks (why? They are just sending a bloody form!)
Finally got the form, completed it, sent it back within a couple of days.
They sent a letter to say we hadn't returned it (we had), I called again. Same rigmarole getting through. They passed us around before saying that, actually, they had it back, but hadn't processed it and we would hear about an appointment in the next day or two.
Nothing.
Called again.
Oh. We still haven't processed this form because we have 2 phone numbers for you.
Yep. Mine and DS's. You can use either. Process the bloody form!
Nothing.
Called again. Same shenanigans.
Yes. We've processed it. Don't know why you haven't had a text. You need an assessment, you will be sent an appointment
Nothing.
Called again.
No assessment required. You'll hear soon.
Nothing.
I sort of gave up at this point.
About a month later, money appeared in DS's account. No letter sent. No information. Just money.
Absolute bloody shambles. It's as if it's deliberate.
I WISH they would move it all online so people can log on and check the status of the application straight away. It surely can't be so difficult in 2025, for heaven's sake.
