I am starting to tell that Comcast or actually Xfinity at Miami, Florida (Metro Dade area) has a secret agenda to get rid of veteran technician that do really know how to fix a problem .
Comcast is getting from bad to worst since the new management took over Mr Hernandez (old line tech manager and now general manager); his new idea or concept of seen this work place. It is firing the old and very professional technician that this place used to have before. In additional anyone of those could has at least no less than 7 years old of hard job and very useful experience. which is no on his mind. the way he seen this place is like this saying "brute force" getting fresh people with no clue of troubleshooting a bad noise, a low noise margin or even report a problem on the line, in the other hand he prefer that those rookies technician spent hour inventing the wheel .installing new cable over and over,replacing stb (cable box) and never will get to the point or close to the problem,because there is no set of mind to fix a problem'
I am no hiding the true if one of you that are reading me now,Have seen those guys replacing new lines; but the problem persist and in additional take more from your own time to wait for them in a new appointment that probably will ran late like always does their tech.and will never end the signal issue
