Fiber Drop Not Buried

I've had ATT UVerse since February\March of 2018. The fiber drop to my house is still on top of the ground. Spent well over an hour chatting online several weeks ago with someone from ATT who said they would send out a tech to "look" at it. Tech (Chase) finally showed up, apologized for this install "slipping through the cracks" and said he would create a work order to have the line installed quickly. That was several weeks ago and still the line is on top of the ground. The tech gave me his cell number which i have texted him as a follow up. No response. What should i do? Plus, as time has passed, my main TV next to the gateway has some ghosting and flickering. We are at the very end of a fiber run and i wonder if the signal is being compromised by something? The reason I switched from WOW was they finally admitted that I had a weak signal (also at the end of a cable run) which also caused ghosting in the TV so i switched to ATT hoping for better signal. Can't say anything has changed. And the wireless signal in the house....don't even get me started.
