Pacesetter Homes

I think Pacesetter Homes was intend to ignore its responsibility and don't want to fix the problem, just delay till the house warranty expired . I moved in in July 21, 2015, the warranty will be expired in July ,2016.
When we had moved in the new house for a few days, we found there isn't a TV/ CABLE Plug-in in the bonus room. However after we checked the plan we signed off , it shows there is a sign of TV/CABLE Plug- in in the bonus room. Because of the missing, we contact the builder -Pacesetter Homes many times, it assigned the electrical subcontractor came to my house and the contractor said the plan which was provided to them by Pacesetter was without the TV/CABLE plug-in at all. Then we contacted again Pacesetter Homes by phone , by e-mails many times, I called them , the line was either in busy or no body picked up the phone call , just let me leave a message, I left the message, no body gave me a phone call back.
I sent the -emails and tried to have the problem solved, nobody have given me any response.Since we sent the first e-mail to report the issue, more than half a year passed, the problem hasn't been processed.
