Line till out of order

Our line was reported as faulty on the 11th aug. when I phoned 2days later to find out they told me they are working on the line, next day told me they are working on the exchange, for 5days I've been told they are working on it, the sixth day they told me it actually hasn't even been handed over to q technician?! I have spoken to 18different call centre assistants and 5 managers -they \estemate"it Wld take another 10days to fix my line??"
