Line not moved even though booked

I received a SMS on the 27th November saying that my line was going to be moved to an address that we were not moving to. This is after I logged our move with the address three times online over the past month. After a frustrating 45mim call to the call centre I was told it was updated and I would be contacted on the 30th by the technician. Today I was told that because the address had changed they were still testing? We still don't have a date for my line to be moved and no technician has contacted us. Our line needs to move. I use the adsl for business purposes hence me logging my first request for the move 4 weeks ago. I need feedback please.
