Terrible Customer Experience

I app**** for a line on the 20th of December 2017. There was a crackling noise on the line and i report this fault in the first week of January around the same time when i noticed that there was an issue. I am a blind person and i requested for a technician to be sent out to help resolve the issue and i am still waiting. Each time i do a follow up i get told that the query is closed or that there is a technician on the way - my query was not resolved (no technician has come out) and i would appreciate it if i could get someone to resolve this as soon as possible.
