Cancellation of Telkom Mobile contract

I am trying desperately to cancel my two year Telkom Mobile contract which ended in 2013. It has now been moved onto a month to month contract. I called the help line on Sunday the 24th January to enquire how to cancel my contract to move it to prepaid. Your female consultant was extremely helpful and friendly and told me to email a filled in cancellation form to the email address: [Email Removed] . I filled in the form and sent it along with proof of ID to the above address on Thursday the 28th January. I STILL have not had any response to whether it has been received- I don. I am totally shocked and thought this would have been cancelled already. I do not even have a case number to refer to! I live in Fish Hoek and our Telkom branch closed down last year. This means that I can't even go to a branch near me to sort this out! I was ensured on the phone by your friendly and helpful consultant that this would be sorted! I am extremely disappointed! Please contact me as I would like this to be cancelled!!! I have been a loyal customer and have several contracts with you! I expect you to value my support and respond to my cancellation immediately! Please sort this out!
