Telkom's Social Media Network Follow-up also useless!

On the 11th March 2016 I received an email from Telkom, offering a free Internet SIM card for their Integrated Data Sevices. On this email I had to click a link to indicate whether I want this SIM card or not. I clicked the link and rep**** to the affirmative. Got a screen which thanked me. After waiting a month I tried to make telephonic enquiries and got the normal, well known responses we are so used to these days: Hugh? Eish! Can't help you! So I reported the matter on this platform the beginning of April, and received a reply from Telkom's Social Media response team to the effect that they would investigate and report back. Now it's a month later, and still no response. I would really like to know why Telkom employ people who do not have the foggiest idea of customer service, not even to mention the lack of knowledge about their own products. Ia there a legal way in which we can ban Telkom permanently?
