Empty promises

I am relocating and asked for my line to be migrated. At first there was a confusion with the address. On 09 Dec I was told that the installation will be done within 1 to 7 days. When I phoned again on the 17 th Dec I was told that the line provider has closed and my line would only be installed after 7 Jan. I need to start working from home on the 19 Dec for and need internet to be able to work.
