ESA phone call

Hi. I’ve been on ESA in the support group for the last 4 years.
Today I got a phone call from ESA and the woman said she was ringing about my ESA , I told her that there was someone at the door, and she said she would ring me back.
I’m afraid I didn’t answer the phone as I was panicking!
Could they be saying that they are changing my benefit or putting me on Universal Credit.
I get the high mobility section of PIP. As I have had spinal fusion and can’t walk hardly at all. Any ideas about this would appreciated as I’m really stressing. TIA

Thanks Gordon but she hasn’t rung back and her number was withheld.
So I’m going to have to wait until she rings again. Unless you think I should pre-empt her and ring them? But I don’t have her name or any information.

Hi Gordon I have received an Re-assessment form for ESA. I’m getting contributions ESA, And they are asking to see if I am eligible for income related ESA from February 2014.They say they are looking to see if I’m entitled to extra payments and premiums.
I have too much savings to be on Income related ESA

They have sent me an ESA3 form And in the letter it says there are four reasons why you would not qualify for income related ESA and one of them is about how much savings you’ve got.
The letter says you do not need to fill in this form if during the whole time and now you do not qualify.

So do I say I have too much savings and not fill in the form
or fill in the form .
My health has deteriorated a lot in the last 3 years and I should have told them I guess but nobody was sure of the outcome and things have only got worse.
It also states in the letter your savings will not affect your contribution based ESA.
So any advice would be helpful
