Waiting over a month for line installation.

I had to move suddenly to a temporary residence due to new owner wanting to move in. I cancelled ADSL and put my telephone account on hold. <br> <br> Now requested to have my line reinstated at my current residence (13 July 2015), and have yet to receive any order confirmation or installation date one month later. I've been trying to followup on twitter, but the only responses I get is are apologies and that \it will be escalated"? <br> <br> How many times does it need to be escalated before I get an installation date? <br> <br> Im upset because for the last 4 months I've been paying for a telephone line thats not installed and obviously not using"
