waiting for line to be installed

Im waiting for my adsl line to be installed order no. *** the first appointment they notified me of the date and time, the guy said they first have to order the poles and then they will schedule another appointment. They were here on Thursdays 1/10/15 without letting me know and told the neighbour that they will come the following day, if they told me they were coming i would've been here. So friday i called ***, the number they send me on a previous sms for appointments. The lady told me there are a appointment for the Friday so they should come. She told me she will just call the installation team to confirm and call me back. Still waiting on Monday morning for anybody to just give me a date and time. This number is also not available the whole morning. This internet is URGENTLY needed for studies. Now im taking leave from work waiting for someone to tell me when they will finish my line, to scared to leave the house, maybe they will arrive again without appointment and ill miss them again. Im extremely disappointed with the service i got so far.
