Internet problems for 15 days

I have been having problems with my internet since 30/11/2015...there have been 15 messages back and front where they just say \ we will sort it out promptly"sorry fr the inconvenience. This has been going on for 2weeks where all they say is we will look into...no technician. No phone calls. My wifi drop minutes on and. I have had to buy data multiple times and yet they dont do anything. This is pathetic. No regard for their customers. What exactly am i paying for if i cant access the internet. I have proof of all the messages. They dont come back to me"
