Faulty WiFi (ADSL)

It has been 6 full weeks that I have reported a faulty WiFi (no internet). I have reported this every week. My landline number is ********** 108. I also escalated my problem to the CEO at this number - ********** 473 *** without any resolution of my problem. I am ever promised that a technician or someone from the Cable department will call me but that does not happen.
