DWP phone call re ESA assessment

Hello Gordon I have just come off the phone from DWP trying to get my ESA reinstated and have been told they are waiting notification from the Tribunal Service. But this was sent 23rd June (I checked) along with my own notification. They have the fit note on record I sent and I included in that letter a copy of the Tribunal letter. The person I spoke to was insistent she was correct and just kept saying the same thing. Do you think I should ask to speak to a manager at this stage, or is it normal to take this long to put an ESA claim back in payment?

Your advice much appreciated

Hi Gordon I have yet to go to tribunal, I want my ESA reinstated at the assessment rate whilst waiting for a date to go to my appeal! I shall take your comments as a positive omen!
I called back again and spoke to someone who was more helpful. I have been told to expect a call back, my request has been emailed through apparently. Lets hope so.
Anyway will keep you posted and thank you for your ongoing support

Hello again Gordon, the DWP did not call me back, no surprise I guess, I then rang again, waited 40 minutes to get through and have been told the request for a call back had not reached the right department yet! So presume they are snowed under but would be more helpful to not promise the return phone call within time constraints they can not currently deliver.
Now been told I will receive a call back by 9.33 am tomorrow . They have the Tribunal notification and fit note they just have done nothing about it and presume they won't unless I keep ringing.
I am finding this part of the process really stressful even though having been through an appeal previously so sort of knew what to expect, persistence seems to be the only way forward.

Lets see if I get the phone call tomorrow.
