throttling speeds for mobile on a new billing cycle

I am on Xfinity Mobile's Unlimited plan. Apparently with the last billing cycle, I went over the 30 Gb limit and my speed was throttled to 1-2 Mbps . Even after the billing cycle was renewed, my speeds remain throttled at 1-2 Mbps. I opened a ticket and after 2 weeks, this has still not been resolved. They keep connecting me to their call center in the Philipines where they give me the same tired advice of resetting the phone, the Network settings, reinstalling my eSim etc. They absolutely refuse to escalate the ticket. How can I reach a manager or a dedicated tech team with my ticket? Or at the very least, a call center rep in the US? In the past, I've seen the US reps to be more responsive.
