Lowe's of Elizabeth City, NC Window Install/Contractor Damage Elizabeth City North Carolina

Had a 15 window install that is still incomplete. The contractor damaged a mulled window, damaged paneling in a bedroom, put a hole in my bathroom wall, put roofing nails in paneling, put roofing nails in siding. Told contractor the workmanship was unexceptable and his staff started running around with their heads cut off and hasn't been back since. They ordered a new mulled window that has been sitting at the Lowe's store since Dec. 2017. Dec. 2017 started contacting the corporate office about damages and also contacted the installer about my complaints, his response was "Oh, well", I ended the conversation. To this date, March 2018, the damages have gotten worse. I have window leaks, water running down kitchen wall, damaged floor from water, water in downstairs wall, 3 bedrooms with damaged paneling, mold and mildew has set in. So bad, if I stay in there 30 minutes I leave with a sore throat.  Called different Lowe's stores 60+ times with them only telling me to contact the corporate office which was not doing anything,but finally found a e-mail address to one of the BOD on the iinternet and sent him some pictures of the damages?. Their insurance contacted me in Feb 2018, had an adjustor out on the 27th of Feb. 2018, now insurance is stalling just like the corporate office/Project Coordinator. Then March 2018, the contractor insurance gets intouch with me, that was almost 3 weeks ago, and nothing since. On Lowe's proposal it states "All installation services are guaranteed by Lowe's labor warranty" and "Professional installation available through independent contractors licensed and registered where applicable." The job is still incomplete to this date March 25, 2018 and more damages continue every day. I researched the contractor on the SOSNC website to find that he has two company's that only does, fencing, siding and roofing. Now how did he get a window install job? To much to even list and my house is destroyed by negligence and incompitience, not only by the the contractor but by Lowe's also.
