Esa98 letter

About 5 weeks ago I received a migratory notice from ESA to Universal Credit.
I submitted my universal credit online.
I received a letter from my local council saying that my housing benefit was stopping and to therefore apply for help with my housing costs through my universal credit application,
so that was what I did.

Today I received from the DWP ESA a letter ESA98 informing me that my income related ESA had ended that Inhad been transferred to contribution based ESA and that this too was ending and I was moving over to New Style ESA.
I am very confused because I had no advance warning of this happening.
I am severely disabled and essentially bed bound.
I am totally reliant on carers - I get enhanced PIP
Daily living and mobility. I was getting income related ESA in the Support Group and was also getting the severe disability premium.
This letter talks about getting to an interview with a work coach at a job centre - when I have only physically left my home once in 2 and half years.
That trip out was to go the hospital to have an MRI scan to monitor my worsening brain tumour (acoustic neuroma) I have so many other illnesses and serious conditions. Why are the DWP sending me this letter.
Am I better challenging this ESA switch - or closing my ESA claim altogether ?
And falling back on universal credit.
I am clearly incapable of work and my life expectancy though not terminal is not good.
My universal credit claim has come through,
I have been awarded transitional benefits,
but the esa has been deducted.
I would be very grateful if someone could advise me as to what is happening and what I should do
with regard to the ESA switch first from income related to contribution based to new style ESA.

Thanks David for your advice.
Much appreciated.

Am I right then in thinking that although my ESA was always described as
Income related ESA.

Having not worked due to illness and disability for 20 years or so.
I was originally on Incapacity Benefit.

that it was always a mixture of both
Contributions ESA and Income related ESA all along.

This ESA98 letter clearly states that my
"Income related" ESA stopped on the 23/3/2025
That my now contributions based ESA
(That I didn't think I had)
will now change to the New Style ESA.
on the 24/3/2025

I expected my income related ESA benefit to close on the 24/3/2024
2 weeks after the submission of my universal credit claim.

Why didn't I go straight to Universal credit to cover the esa.
And instead was put on
(or transferred to) a contributions based ESAin order then to be out straight on to the New Style ESA.

Why was it fine this way ?
They know that I am on the support group, what is their motive
for putting me on this.
And threaten me to work with a work Coach.
I am sorry I just remain confused about why they have done this.
Yesterday I rang DWP ESA and they says that I could close my esa chain and then inform universal credit
that I have done this - but others have said to me you need to ask DWP/ESA
if this was a mistake of theirs.
Any advice would be much appreciated.
Regards
David

Thanks for your advice David.
I originally had incapacity benefit and then over 10 years ago I was switched over to income related esa.
It has never been referred to as
Contributions based ESA and as such that has confused me.
The ESA98 letter informed retrospectively that my income related esa was stopped on the 23/03/2025.
That my contributions based esa
was switched to new style esa on the
24/4/25.

Is this some of trick or mistake
of theirs ?

Why don't I just go to straight to universal credit for everything.
I am very confused.
DWP esa suggested I close my esa claim altogether.
