No Reponse on Order Cancellation

I was called by a sell direct agent to sell me a Huawei Wifi router on a 20 Gigs All Networks Data package for R399 per month. I agreed to the package and the device was sent to me. Upon recieving the device I called their office line several times for activation and there was no answer,I eventually got through to sell direct and they told me that they could not activate my sim card because Telkom had advised them to discontinue the package that they sold to me. Now they wanted to offer me a new package of 20 gigs Telkom Data, which I did not agree to and I informed the activations consultant that I agreed to buying the initial package because it offered \All Networks Data"and because they are now changing their offering to me I asked to have the order cancelled as this is breach of contract on their part. The consultant 'Tashreeq\"" asked me to send an email informing them about my intention to cancel the order and have the device collected by sell direct. I sent the cancellation email on 09 September 2015 to the email adress that Tashreeq gave me"
