Worst service ever!!!!

My voice line was installed on the 25th of may 2015. when the technician arrived I told him that the consultant said I must tell him the line must be adsl activated, he advised me that he cannot do the switching until the technical department advised him to but said it takes like 10 min at the central. On the 26,27 I called saying it takes 24hours, right on Thursday the 28th a consultant pushed the order thru telling me within 24 hours I could call mweb to activate. till today no active adsl line when I phoned again today they said again 7-21 working days to switch one little wire at central so I don't understand who knows actually what they are telling me and how long its going to take... for one wire to be switched at the central. Can't believe its so frustrating and poor service!!!
