Cable out since December 8th

They came out to “update” service on December 8,since then I’ve had no cable,only pixels on all channels.I’ve spoken with 4 different representatives,been told they would be out 3 different times and we are still out.Now I have to wait till December 22nd to have someone out,this is totally unacceptable.I need this fixed immediately,the customer service is a complete joke.
