No internet service AND now a 4th repair man coming in 3 weeks😫

I am beyond frustrated.   I recently subscribed to the U200 everything package. Previously I had only internet, no TV, and had no problems.  But since subscribing to the new package 3 weeks ago, I have had intermittent service.  Quite frankly, it works less than it does!   I have had numerous, lengthy phone calls with AT&T and 3 service calls.   Do you understand the amount of time that requires from my work, my family, my time?  I find it unacceptable.  And, now, I have yet another repair man coming to ‘take a look.’   Does your CEO have such time?  As an educator for a large school district, I haven’t anymore time for this, AND my voice will speak loudly to my fellow educators about my experience with AT&T.   Help me, I just want what I’m paying for.
