Cell Tower Issue - Horrible Data Speed - Please ESCALATE and FIX ASAP

This needs to be escalated to get fix ASAP real bad. I am to the point to switch carrier.

I communicated with Marilyn (AT&T Community Specialist) via PM for 2 weeks. Although she spent a lot of efforts helping, none is help. She mentioned an outage was in the area, then confirmed it fixed. But the issue never fixed. I get a new sim card, it doesn't fix it. Everyone in my building who uses AT&T have the same issue.

I get 2 bars out of 4. Regular call/ SMS message is fine but cellular data speed is horrible, super slow (<2 mbps measured consistently) , almost none since the past weeks. This started to happen 4 weeks ago.

Only in the area where I am at, It worked great if I go to the other side of town which I bet I pick it up from different cell tower.

Issue Location

N 6th St, Fort Smith, AR 72904

Same issue in the mapped area (Attached). Red rectangle is the area that having issue. I measured my speed different points on the red lines. Same issue.

I also attached the latest screenshot of the signal strength measured by Field Test mode on my iPhone 12 Pro. It's a bad numbers.
