ESA payment delay 2021

I put an application for Esa based SSP on the 26th April and I still have not got any letters or calls from the jobcenter. I have rang the DWP numerous times and had 3 escalations put on the claim which is all there and sorted, the DWP have told me I need a claimant commitment meeting with my local jobcentre but everything time they tell me they will message the JC to ring me back within 24 hours it never happens . Anyone have any idea why its taking more than 6 weeks ?
