To Rain or not to Rain that is the dilemma

Rain by me is no thunder storm but rather a dry desert drizzle. Since receipt of my sim 3 months ago speed was below par, but of recent it is a drizzle. A few blocks up the road there are amazing speeds. There are a few of their towers around me providing coverage according to their maps. I have tried the usual reset device and moved around my home, with no success. I have tried expensive outdoor antennas so tall aircraft swerve to miss them and then occasionally there is a burst of speed, otherwise no Rain. Support takes more than two weeks to respond to emails and then they just mark as resolved.

Shocking reception, no technical support.
