Relocation of landline

had called in on the 30 Oct to relocate my line and I was assisted by a very friendly person, she assured me that the monday following a technician will contact me to do the installation. Monday came and went with no news, I called in on Tuesday, 3 Nov and I was told that the technician has a problem and was sorting this out. No one hd contacted me regarding this and I was left waiting. I have heard no news since, I called in today (monday 9 Nov) , a week later and the call centre agent tells me that there is a 7 to 21 day waiting period on installation- why has no one communicated this to me before ? I spoke to a Supervisor by the name of Linda and he promised to call me back on my cell last week Tuesday, I have't received any calls.This is PATHETIC Service!
