Telkom relocates ADSL line on the wrong date when date was confirmed in writing

I communicated to Telkom that I will be moving house on the 30TH AUGUST and requested the relocation on that day, being 30 AUGUST. They cancelled my internet TODAY 20 August. I work from home and have to have internet. I also work in the evening and have to have access. The response was that it is "pending" and they cannot reconnect the internet. I have received emails from Telkom to which I responded confirming in writing that the relocation was to be done on the 30th August.
