Cancelled Data Account in March yet still Billed.

In March before month end, I went to Telkom KeyWest to Cancel the Data Portion of my internet which is with Telkom. (2mb uncapped account). I made it clear that I only want the Telephone line and DSL line to remain active. I was told it was cancelled and that I have to pay The existing bill which I did and that the Data portion will be cancelled the next month. This month I received my monthly statement and to my surprise the data portion is still there? I went to Key West this week on Monday and was told that indeed we did cancel the data Portion in March but the staff there did something wrong. I was told the person who is responsible for the cancellation is the manager Carolina de Witt ***) and that my internet will be cut off on Tuesday. On Tuesday my internet was cut off. I signed up with afrihost so that they Manage my DSL line. They were denied by telkom, and Telkom's reason is that I still have an active Data account with them.. When I already cancelled it in MARCH? and it is off since Tuesday? I have no working Telkom Data account any more so Why am i Being told otherwise? Also please correct my bill as I am not paying something I Cancelled .<br> ***
