Ordered to move line - No Delivery

I have ordered Telkom to move my line to another suburb as I have moved to another house.

The order was requested on 5 April 2018 and it is now 22 May 2018 and still no delivery of services received. Telkom is expecting me to pay them the full account for no services received.

According to website, we have to give a months notice and it is more than a month now.

I do understand that my number will change, which is not a problem. My problem is, the time it take to install a line. I never ever had to wait so long for a line to be installed. In the past, when I requested to install n new line, it was done within 2 weeks.
