Over a Year for an ADSL Installation

We ordered an ADSL Line for our home in Blue Hills Country Estate. They sent a gentlemen by the name Clifford Mogano in August, he said he can't find the line inside the property and that we should get an electrician to trace the line. We got one, traced the line at our cost, we called Clifford Mogano back, he said he was no longer in the area, we should speak to Shadrack Machethe who suddenly didn't know anything about our order. After sending him mails of what he had sent us he said we will come on Monday the 1 December 2015 and to date we still waiting. We had numerous sms confirming the various installation dates.
