Pip review, how much longer?

Hi. I had my review forms through in October and they were confirmed to be reviewed on the 18th of that month. I have called multiple times since then asking for an update and I just keep getting told its waiting to go to the assesors. I'm not surprised I need another assesment as my needs have massively changed since my original claim and I'm not sure I even got the right amount the first time round.

My mobility is getting worse by the day and I'm struggling so much right now. It feels like I'm constantly in survival mode. I have a manual nhs wheelchair but I'm desperate for an electric one as I can't push myself far at all so I'm basically stuck. I cant afford one so I'm hoping I'll get mobility this time and can use that money. I currently only get standard daily living.

Does anyone know how much longer I could be waiting? It's been over 7 months and that doesn't even include the wait after the assesment. The stress is making me feel even worse than ever and I just desperately need it to be done.

Thank you

I sent mine in February 21 they keep telling me my claim isn't up till December 21. Which is wrong because last time I had to go Infront of a tribunal.
