New lines to be installed

They are useless, was on hold with on there call cntr for more than 20min, no answer. Have been waiting for almost 3 mnths for technicians to come out and install new lines as we need new lines before a voiceline can be installed. The shop in the mall is also useless, cancelled our wifi and took us 4 mnths just to cancel and only to find out we have paid 4 mnths extra on a contract that could have been stopped long ago. I need this resolved asap and be sorted.
