BAD SERVICE

My line was cancel and i wanted to re instate the line i was put from pillar to post its been 3 weeks since i was told by the 1st agent that they have escalated the matter. then was told they awaiting Vumatel to clear the line when i called Vumatel they told me there was nothing that was escalated to them. Yesterday was told to do a migration for my line and it will take 48 hours for it to be cleared still nothing. Today i wanted to knw how far and was told the line need to be cleared with Vuma so they can migrate my line. i mean like wow called vumatel again same story they never log my line to cleared. This is the worse ISP
