Wifi connection

I'm very disappointed with your service it's almost a month that I have been waiting for installation and I have been calling several times to get an update on the progress I was told they would come out on the 5th of December they told me that they have called me but the phone was off I found that strange because my phone was on all the time I didn't get any missed calls or voice mail as proof that they called me I called them again today but there was no answer right now I feel like canceling and get a better service provider
