Lat of service

I processed a cancellation for a Telkom line some 2 months ago as I have 67 contracts and were consolidating the contracts. I have not heard anything and as it is a 30 day notice more than 30 days have passed and I am still getting billed for the cancellation. I went online and it states that the request is already logged.

I processed another cancellation today for another Telkom mobile line that I have I am a bit worried that it will be the same.

will someone tell me what is going on as these contracts are device free.
