MM ESA to UC: Initial appointment, no response re reasonable adjustment

I used CAB Help to Claim, have completed all the To Do items & initiated my claim.

On Saturday 7 June I received notice in my journal of an in-person appointment at the local Job Centre which I cannot access for mobility reasons (there's no Blue Badge or indeed any parking).

I've replied on 8 June & again today requesting a reasonable adjustment to a telephone interview under the Equality Act 2010 and why (severe pain, lasting effects) as suggested elsewhere on your invaluable forum.

No-one has responded, the appointment is for tomorrow, and I'm struggling with anxiety that they'll sanction me.

Please advise, thank you.

Yes, Support Group with DIG & SDP.
I receive PIP (Standard DL, Enhanced Mobility) and live alone without a carer.
Sorry if this is a duplicate reply - I got a message about 'flooding' and was confused.

Hello David

Thank you for your helpful advice.
I called CAB Help to Claim, explained the situation, and they offered to make a 3-way call with the DWP and advocate for me. It only took 5 minutes to get through! The DWP agent said he'd inform my local Job Centre.

Later today, I checked my journal: two messages.
Firstly, can I email copy documents as itemised to local Job Centre - fair enough;
Secondly, 'they hope I'm soon better, a new appointment is booked for same location in a week's time'.

Please advise: how do I get them to understand I need a phone appointment, & to pin a note on my file as requested?
