Cox Gigablast over copper

Ok so now as an update to this little fiasco ive had 5 tech visits trying to solve internet issues . The second to last tech came out and said there is ingress on the line and that the signal has 6-9 dBmV drop on the line from the node 3 houses down from me, which with lot size here that is about 135 to 150 feet and that they need to rerun the cable to my house. He put in a power amp using my outlet to increase the signal power and said he had to place a work order to have the line reran. Well within two days the power amp kept tripping the gfci outlet and no power to amp meant no signal no internet. This was after the tec drove to the wrong house and closed the ticket without ever coming to my place. I had to call cox customer support and their shift supervisor got involved to install it. so again a 5th tec came out to replace the power amp. while talking to him e stated that there was no work order to replace line so had had to rerun tests to vary the power drop was a line issue and not a port issue in the network hub. he left and stated he would have the work order issuedits now been over a month and no repairs yet on the line how do i know simple cuz they couldnt find where it was supposed to be in my yard  since it was installed 29 years ago underground. So know ive got this.

yeah thats 396 billion plus octets on channel 13 and 706 million on channel 27 the rest of the channels are like 18-51 million octets. I've 26 profile changes on my modem and and 18 no ranging response T3 timeouts in 16 days each one of which locks me out of my modem and closes me out from real time gaming movies and causes me to restart my vpn all this for 170 dollars amonth for unlimited useless 1 gig gigablast

so the subdivision i live in in almost 30 years old so maybe its time cox comes out and does some infrastructure work they pulled fiber pat my backyard about 10 years ago but apparently i cant get in my area 

ok so after 3 visits from cox techs one of which was here for a whopping 7 minutes between supposedly calling to notify they were here  one hour and 42 minutes into my window and cancelling the ticket they reworked all connections in outside supply box on my house replaced connectors  replaced a section of coax that transitions underground swapped out the arris tm3402a im still getting streaming freezes on gigablast service and disconnects here is the modem stats from the last 37 hours

ive now got  increase of about 6dBmV on the channels and a loss of 7dB in the snr and still getting errors 4 No Ranging Response received - T3 time-out 6  US profile assignment change. 3 CM-STATUS message sent. Event Type Code: 16  and 4 CM-STATUS message sent. Event Type Code: 24

Hi bm,

I'm sorry you've been having this experience. Looking at your log, I'm in agreement. SNR and all is looking fine, but those errors and slight power adjustments need to be looked into. I would advise the basics like checking to ensure the connections are tight and bypassing any visible splitters between the modem and cable outlet. If you've already completed those steps, I would recommend a tech visit. If you would like to arrange that or need further assistance, please email me at cox.help@cox.com.

Thank you. 

File an FCC complaint. They don't respect their customers. They only listen to the threat of FCC fines. They are a monopoly and have no reason to care. The will have someone with more authority contact you.

Oops forgot o add when i run speed test to cox phoenix it can be anywhere from 450-750Mbps download and i'm getting  15-25Mbps. Yes i know the downoads are slow but right now that could be all the traffic on my wireless network with streaming videos but the upload speed is nowhere near what it should be since COX has upped it to 100Mbps as i said earlier this all has rapidly degraded in the last 2 weeks since so called maintenance in my area
