I need to speak with a Actual supervisor. I need access to direct messaging. I have network issues. I have plan issues.

I have tried everything. I have made at least 20 calls.  And spent 40 hours on the phone with the phone reps and they tell me to talk to someone else or lie to me. Ive asked for supervisors and I Have had NOTHING BUT problems. Ive been to the store 5 times too.
