Giving notice of a contract

<p>I had a 24mth phone cellphone contract with Telkom, and on the 13th of June, realised the contract has come to an end.</p> <p>I then send an email to ********** to request the service be cancelled. I never received a response that they received my request, nor a reference number, nothing!!</p> <p>This is how Telkom does business: Quick to sell you something, but extremely painful to deal with when you submit a cancellation. </p>
