Service Tech

My Service tech was out 9/19 to fix my phone line to my modem WELL he set everything up great HOWEVER hours after he left I lost my land line I'm UNABLE to use my land line that I assumed was fixed. I called tech support he reset on his end and still no land line for me. I then attempted to get a tech back and was informed I have to WAIT for a day to get someone out. I would like a REAL human with some authority to text me regarding my horrible experience
