Very angry

Reported that my internet is not working at 9.30 in the morning this had been off since 12 am. Was told that I would receive a call back. Only for me to call back after and hour to find out what is going on. Then I was told they are looking into it. At 12 a call out was logged and at 13h00 still no feed back. At 14h00 get a call to say that there is no one available to attend to this problem. I call back asking why they have no one on std by and I am told they book calls a week in advance. I am very angry as i use this line to work from home after hours and on weekends. I am now so frustrated as I do not know when it will be sorted out and I am sitting with an unfinished report due this evening....
