Excuses change every day

If at all possible do not get fibre with this company at all, yesterday I phoned about a simple circuit release, since the previous tenant did not cancel their service. Provided them with the new lease agreement etc to prove that I am the new tenant. Yesterday when I phoned they said that it would take 24 to 48 hours. Phoned today and I was told the circuit is still not released and the timeframe is now 72 hours. This is unacceptable as their own staff do not even know the service providers turnaround times and this is employees of Vumatel. How long can it really take to release a circuit?
