Need live support

Good evening @user_2kw309, and thank you for reaching out on our Forums regarding the phone calls you received after sending an email. Unfortunately, we do not have access to those emails on this platform but we are happy to help with any account or service issues you have been experiencing. Can you tell us a bit more about your account concerns? 

To be fair I have reported to fcc and Bbb. However if you can handle . Thanks for trying to help. The problem isn't just a simple router or signal issue—it's a duplicate account glitch that's been in the system for over 6 years and has caused every single problem I've had. Here's the full background so you can see why standard fixes (password resets, reboots, etc.) never work:
Day 1 (over 6 years ago): I personally returned my deceased father's old equipment in-store while picking up my new router. The system showed duplicate accounts at the same address, so my work order didn't appear. I spent 1.5 hours in the store, but they gave me the equipment anyway. The duplicate was never permanently removed—this is the root of everything.
Phone activation: Took nearly 2 weeks and 8–10 hours on calls. Only fixed when one rep spotted the duplicate and cleared it temporarily.
After dad's passing: Duplicate caused bogus charges for nonexistent services. My mother got collections threats for ~$800 bill (you mysteriously applied $600 credit, demanded only ~$200). Despite proof of returned equipment, never fully resolved—pure harassment during grief.
Ongoing issues:
App/website always says "not preferred/primary holder" (I'm the only user/payer). Blocks full access, management, troubleshooting, self-service, and all Rewards perks/opportunities.
Recently discovered: My TV/devices are logged into a completely different account (Xfinity ID: <Edited for PII>, email: <Edited for PII) — I've never created this, and the last 4 digits don't match my account. This is clearly my father's old duplicate still active.
Service problems: Internet speeds stuck low (~400 Mbps max on higher plan), constant drops/fluctuations, require frequent router reboots. Landline calls don't ring (voicemail only), and during calls it cuts out every ~15 seconds—impossible to talk.
Support history: Hundreds of calls over years—explained duplicate every time, always told just "reset password" (even specialists). Emails ignored, chats useless, offshore reps ineffective.
I escalated to executive team (Thomas Karinshak) Dec 22–24 and have now filed complaints with FCC and BBB.
To finally fix this, I need someone with authority to:
Permanently remove/merge the duplicate account (<Edited for PII>) and grant me full primary/preferred access.
Send me a new upgraded router (I can't order myself due to the block).
Switch landline to reliable WiFi-based service if possible.
Shut off TV service now and arrange return of the Flex box.
Process Xfinity Mobile service and order the phone (third attempt).
Given the aggravation, hundreds of hours wasted, missed Rewards benefits, and harassment during my dad's passing, I expect fair compensation to make this right (bill credits, service discounts, mobile assistance, or even a free phone—something meaningful, because even a free phone wouldn't fully cover what I've been through).
Please escalate this to someone who can do all of the above, or let me know next steps immediately.
Thanks,
