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.
