False advertising and lack of response

I have had it with Telkom!! Last month my partner and I decided to get our new phones through Telkom. In the brochure it clearly states that you receive uncapped data with your phone until the end of June if you have the smartplan 100. In January both of our 1gig capped and no uncapped data. Logged a call with the call centre on the 27th of Jan. We have had NO feedback AT ALL!!! We have had to buy additional data twice for both phones and have not received a refund for this either!!! False advertising seems to be happening here and Telkom is hiding behind their call center unable to phone us to resolve this matter!
