Incompetence all round

I bought an LTE product at Telkom mobile for Internet access in our new home. Spent an hour and a half Instore and walked out with nothing but paper work...my contract would be approved within 3 working days.<br> <br> I received the product a week and a half later only to find out that it did not work. I then called and informed the agent. He escalated the order so that a technician would come out as soon as possible.<br> <br> Two weeks later, I went back to the store to return the product and cancel the contract as I wasn't going to pay for something that I was not using. This was done on 10 April 2015.<br> <br> At the end of that month I received an invoice for the product. I didn't think anything of the invoice at the time as I had already cancelled the contract. On 15 May 2015 the total for the product was deducted. I called in immediately to inquire...my contract had not been cancelled. In this call i instructed the agent to cancel it immediately.<br> <br> Today 2 June, I received another invoice. Immediately I called in...and once again the agent tells me that the contract has not been cancelled (with an attitude might I add).<br> <br> How in heavens name can it still not be cancelled..3 months later...
