Vodacom hiding mistakes by ignoring approved customers

If I could give them less then 1 star. I would. I was approved for a deal, I app**** online. And then nothing from them further when they realised they made an error on their website. I spoke to 4 of their agents. Everyone promising me they will have a manager phone me, this was on Tuesday, I have spent so much on airtime to call and find out what is going on, but nothing from their side. Now that I can send an email to *** to escalate the matter. The email keeps bouncing back to me. I was approved, I sent my documents through and received my reference number. But now that there is an error on their side, they have reverted back to a teenage mentality where if they ignore the problem it will go away. Which is heartbreaking, because they are such a big and successful company you as an individual does not count as a customer. Furthermore, their one sales agent made an inappropriate joke with me when I told her my situation. She told me I will be running around the entire time and they will not give me any feedback. Which I guess was more accurate then I thought. Seeing as it 3 days later and I have received no feedback from them.
