more than 2 weeks later and no feedback

Lodged a complaint with the call center (ref ***) on the 2nd of May 2015 in connection with bad reception at my home.<br> Technician came to my house (no identification, no uniform and really not professional whatsoever and using a cellphone) on the 5th of May and conirmed that the signal was terrible.<br> Since then every time I call nobody can give me any feedback as we are all now awaiting the networks department.<br> 2 weeks later still no feedback.<br> <br> All I want to know is if they will be able to fix the problem and by when we can expect this to be done.<br>
