CONTRIBUTION BASED ESA

Hello all
i feel the need to explain my situation first so you get the picture i was involved in a work related accident 11/2014 resulting in a back injury & nerve damage in arm & hand my employers admitted liability & advised me to seek legal advice. On 05/2016 they terminated my employment after three occupational health sessions (via capita) who advised my employers i would never work in a manual role again.Two MRI Scans revealed degenerative disc disease, spinal doctor said the accident had bought the degenerative disc disease on five years early. I have recieved in the mean time, physiotherapy,acupuncture,radio frequency lesioning,pain management, all to no avail.
I applied for ESA 05/2016 i am still on assessment phase 03/02/2017 i completed the esa50 form on 11/2016 following the guide on from the site.
I also applied for PIP 05/2016 & got Daily living component (Standard) Mobility component (Standard) & Industrial Injuries 20%
I received a letter today from DWP stating that my ESA will stop on 05/2017 because i will have reached the maximum of 365 days that i get contribution - based employment & support allowance i questioned why i haven't been assessed yet? she gave me the phone number to phone the health assessment advisory Service, spoke to them & they said they received my completed esa50 on 14/12/2014 & a decision was made on 24/01/2017 & they are waiting for a date for the assessment he then went on to tell me how decision works, if i am put in the support i will continue to receive ESA, if I'm put in the work-related activity group i will (NOT) receive a payment what so ever & will have to attend a work shop once weekly or the alternative is to sign on for JSA & said all claimants on ESA should be back at work after 12months!!!!!!

PS A few things i forgot to mention:I have worked since the age of 16 (986) & in the 40%tax bracket up until my accident in 2014 when i need some help i just can't get any help: regarding my accident i was referred to a psychiatrist who come to the conclusion that i was suffering from serve anxiety & depression to which i did include in my esa50 form.
I live with my partner who works full time but on minimum wage i guess Dwp take all this into account when it comes to my contribution - based esa
I have nearly lost the house we are renting because of all this, i get up fighting through difficulties,getting up again & again but this time i just feel like giving up. I hope all of the above made some sense.

Thanks for your advice Gordon, the whole process is making me unwell, I've tried my best to get my injury better so i can work, its all i know, but just feel like the dwp think I'm lying, i will keep you updated regarding my assessment

Update i contacted DWP 20/02/17 & explained my contrition based ESA is due to finish soon, Dwp said they will fast track my assessment with Maximus, its now 09/03/17 i phoned DWP this morning & they said we can't fast track your assessment while your still in receipt of payment, I seen to get a different story every time i phone the DWP

Wacky baccy of the strongest amount for the drivelle they tell one and all on the telephone.
I do everything now in writing including registered mail with a legal inclusion stating a response different to what I have expected the answer to (which is included within the letter), is to be sent within 28 working days of the date of this letter. So far this has sufficed.
