Cancellation of contract delayed yet again!

I am trying to cancel my MTN contract, after being a loyal customer for - 20 years . After being told that the contract can only be cancelled by phoning today - I was kept on hold on the 808 number for half an hour - before I could speak to an operator. I was then told that the cancellation office is closed today (the person could not explain why the cancellation office would be closed today of all days). They did offer to phone me back. <br> <br> Why was the cancellation office closed for the day?<br> Why can the service provider not log the contract cancellation request when the customer lodge the request - and ensure that it happens immediately upon expiry of the contract, without wasting the customers time and testing their patience this way? <br> <br> I did not know such bad service existed anywhere!
