Received bill after cancellation of contract

On 5 January 2015, I attended the Umhlanga Gateway store to cancel my mobile phone contract. I completed all forms with a consultant and was told that my contract would be cancelled as from the end of January. No document evidencing cancellation was provided despite my request, although I was given a case number (***).<br> <br> Today, 3 Feb, I received a bill that indicates various amounts due in respect of services for the period 1 February - 29 February 2016. This is unacceptable. I duly cancelled by contract, by giving 1 month notice. No charges for February should be billed to me.<br> <br> I have attempted to contact the call centre twice today, and after being on hold for 10 minutes on each occasion hung up. I have also attempted to initiate an online chat, and waited for a consultant for 15 minutes without receiving a response. I have also attempted to use the send an email function on the Telkom website. I received no confirmation that the email was sent and do not intend waiting for a response when I cannot be sure that the email was sent.<br> <br> Please contact me urgently by email to rectify this issue. If my account is ********ly debited I will expect a full refund from Telkom.
