Bad service from call centre agents and UIF team

I app**** for unemployment benefit on 4th April 2022. I was declined because i needed to submit more documents, which i did and i was advised everything is in order. On 26 May 2022 the status changed to "Completed by Assessor" till today. I have been calling the call centre and the response is they have escalated the issue. Its over 4 months now and im scared my claim will expire. I am not getting an assistance at all.
