how do i go about getting a business to finish a job?

i had AT&T come out for internet & cable service. they had to take a portion of my fence down, dig a 6 foot hole in my backyard to get to the main box. they got everything hooked up & told me they would be out the next day to fill the hole, put back my fence & bury the cables. we never heard a thing from them & we have been on the phone every day trying to get someone to come out. here it is 5 days later & nothing has been done. even though they put a mesh like barrier around the hole, i''m worried that kids will fall into the hole, plus, i have a swimming pool. also, the live cables laying around. i talked to someone yesterday & they gave me a $80.00 credit and reported it to her superiors, but she still said it could take 3 days or so. my wife & i are so frustrated over this. hopefully someone can help us. thanks
