Poor Service/Data in RI/Ma

Recently I've noticed a significant decline in AT&T's coverage to the point that where I normally receive 4 bars of LTE I am getting 4 bars of 4G.  With the 4G, data transfer rates are unbearable to non-existent.  Some days are worse than others, but for the most part this is fairly constituent.  

I use Waze each day to and from work for my 70+ mile ride to and from work.  This tells me which option I need to take.  When I leave the office at the junction of rte 95N/93/N and 128N just outside of Boston where our office sits, I get no data.  On some nights I need to drive 4-5 miles before data will kick and and Waze will finally provide me with my routing information.

It's gotten to the point that after being with AT&T for over 15 years I'm considering switching to Verizon.  This is not what I want to do.  I'd much rather stay with AT&T.  The main problem I have with all of this is that they claim to have invested a great deal of money in the New England market to improve the AT&T backbone signal.
