Cancellation NOT HONOURED!

My account with Telkom ends on 5th September. On 27th August I contacted Telkom to cancel my account, I was told that because my contract ends on 5th September I'd be able to implement the cancellation on 6th September without having to give 30 Days notice. I was told my account would be cancelled and received the following 3 reference numbers for the cancellation: ******12

My account number is: ***

This morning I phone telkom to follow up with my cancellation only to speak to a consultant who doesnt know what she is doing and refused to let me speak to a supervisor - she just dropped the call on me. She told me that my cancellation request wont work (she couldnt tell me why) she says I must do an immediate cancellation but there will be penalty fees app****. Yet she refused to tell me what the penalty fees would be?

So Telkom, how can the first consultant tell me that my account would be cancelled and everything fine and now this second person tells me it wont work and now all of a sudden I must incur penalty fees?

My contract ends on 5th September - I expect to have my account closed from the 6th of September.

I cannot believe was ridiculous this is - how can you send clients confirmation reference numbers for a cancellation request when it hasn't even been honoured?

Very unimpressed and one of the reasons why I want to cancel with Telkom
