Hi Remix
ESA is an indefinite award with scheduled reassessment based on the Prognosis Date completed by the assessor in their report, so your existing ESA award continues in payment until a new Decision is made.
Until you make the phone call you will not know. I have not seen any posts on the forum where making a phone call has triggered a review, at present there is a backlog of cases waiting for a review, DWP are concentrating on new claimants.
