Data cancellation and ADSL Migration

I called Telkom to cancel my Data and move my ADSL line to Mweb, on the 28th Aug 2015. I was told i need to place a 30-day notice. After 30 days they said the ADSL is ready to be moved, its till didn't reflect with Mweb. I asked if the Data has been cancelled, was told i need to send an email for that and it allow 20 days notice period. This was never mentioned to me on my first call that i need to place a different notice for Data cancellation. When i asked whose fault it is that data is not cancelled, agent said he cant help.
