Telkom messed Up my account

on the 19th June I asked Telkom to upgrade my ADSL speed to 4MB Uncapped from 2MB Uncapped and also activated the Telkom unlimited calling plan for 12 Months @R599. <br> <br> On the 23rd I was throttled without any notification and when I asked Telkom why they told me I had reached my 100GB limit which I was not informed of and cannot even find it in the terms and conditions. I decided to cancel only the data portion and I specifically told the consultant that I will move only the data portion to another ISP after 30 days. \Like a woman scorned"Telkom downgraded my speed to 2MB and cancelled my unlimited calling plan. I have been struggling the whole month to get them to upgrade my speed to 4MB and reinstate my calling plan. This has affected my studies and training as I am dependent on the phone and speed. """
