Help from anybody that actually knows what they are doing?

I need help because apparently everyone in the past 3.5 years can’t seem to get it right. I have had issues since i built this house. I have had over 20 techs out in the last 6-8 months.. everyone is going to solve this issue.. Everyone leaves defeated and moves on to the next, easier ticket.  i spend at least 1-2 hrs a week on tech support.. Have over $300 of credit this year alone.. i don’t want any more money..i don’t wont any more techs, i just want something to work that i pay for.  I am 100% it’s a plant issue.. Yet nobody cares about it because last time it only effected 206 people.. Most of which don’t know it’s a issue or what to do about it..  No splitters, brand new RG11 cable, weather tight ends have been cut and placed on more time then I care to think about, 4 new cable mondens in 8 months, 2 new switches, a new AP wifi system. im tired of throwing money at it becuase i got people that cant think logically and blame the first thing they see.   Another "supervisor" i supposed to call/come out soon.. But that’s a weekly occurrence.. it never helps.  here is the lasest logs.
