Unacceptable contract activation time

I app**** for a new tablet contract with Franzelle at Chatz Waverley Plaza on 04/10/2015. I have had the tablet for about a week and a half, but the SIM is still not activated. This is due to a difference in the contract price that I app**** for and the contract agreement I was given. The brochure that I picked the contract out of had the Samsung Galaxy Tab A @ R299.00/month, but the contract agreement was for R249.00/month. I asked Franzelle to sort this matter out. I have spoken to her once since then, and asked her to keep me updated. i have not heard from her in a week. This is my second bad experience with a Chatz branch in as many visits. I do not have wifi at my home, so at the moment I am sitting with a very expensive paperweight. Please help me get this account activated.
