Unfair treatment by Telkom

On the 5th of February 2016 I requested Telkom to terminate my month to month data contract using the termination form. I missed the condition that stated that one month notice period should be provided; I went ahead and requested that the contract be terminated on the 29th of February. After not receiving any communication to acknowledge receipt of my termination letter, I phoned Telkom to find out whether they had received the letter. I was told to wait for 21 days. <br> <br> To my surprise the contract was not terminated on the 29th of February 2016 as per my request. Telkom went ahead and recharged my number with data. Yesterday (7th March 2016) I received an email advising me that the contract has been terminated and that I was invoiced fully for March. Their action meant that I forfeited all the data that I was supposed to use in March but yet I am charged for it. <br> <br> I believe Telkom was supposed to contact me and inform me that they could not cancel the contract on the requested day, I was going to postpone the termination date to the end of March, to allow myself time to use the all the data.
