T-Mobile Home dropping Internet

I have been having same problems which are 1000% not my tower overheating! Its been this way since day 1 and they only offered to refund 1 payment for the issue and I basically have to restart or reset the damn thing 20 times a day it just drops but still shows 2 bars just can't connect to device and drops whatever im doing via internet or streaming TV etc. They 1st said its a device issue and would call back never did though then 2nd said its due to maintenance or working on tower nearby and would call back....and now nothing never heard back amd seems im charged twice in a month for this shotty service and no where near speeds it should be let alone 5G as they said I am and should have in my area before I even ordered it. My bill is $113 i just paid $58 and was told it was no more than $50 a month im so passed off and good luck ever reaching a live person to help they can't even understand what in saying or even listen and no way I can understand them either its always hard to communicate and they say yhey will call back and put in service order but never have
