No service!! 2 x in one week. 3days not fixed yet!

This is the second time in a week that my line has died on me. On Monday morning it was dead and fixed within 4 hours. On Friday morning it was dead again and I reported it. It is now Sunday and nothing has happened, nobody has contacted me and when I complained on their FB page on Saturday morning I was promised feedback. I had to ask 3 more times on Sat for feedback. Every time their response is sorry for the delay we will investigate and give you feedback. It is now Sunday and still no feedback!!!!
