There is one area in Roanoke VA that has terrible LTE service. It's busy intersection with a Kroger that we shop a lot. Signal outside is decent but internet never goes faster than .05Mbps down and zero up. Inside the Kroger LTE switches to 3G. Considering that 3G is going away in 2019, we will be without a phone signal/internet while shopping for groceries. So no calls home to check if we need anything or download coupons.
This is the intersection:
Colonial Ave & Brambleton Ave
Cave Spring, VA 24018

Where should I report this problem?
