UIF 19+ MONTHS

I did an e-filing claim July 2020 after months of trying to follow up I finally talked to someone in January 2021. Documents requested and sent, more phone calls, more "we are escalating your claim" then July 2021 told that there was computer problems in May 2021 and to please resend everything. Resent docs, more phone calls, more escalating which brings me to January 2022 and a request to fill out a form confirming my bank account details which was also to be authorized by my bank which was done and sent on the 13th January 2022 and was confirmed received. Phoned in the beginning of Feb claim is still been escalated which bring me to today. 3 calls each one cut off the last being after I spoke to someone who was checking and put me on hold for 19 min 58 seconds. Can someone tell me how I can talk directly to the department that authorizes the claims?
