Unacceptable contract activation time

I app**** for a new tablet contract along with a contract upgrade on 04/10/2015. Franzelle told me that she was having difficulties loading the new contract on the system, and that she will have all the paperwork ready for me to sign when the devices arrive for collection. A few days later she called me to come collect the devices. Going through the new contract's paperwork, I noticed that the contract price I had app**** for, and the one that was on the actual contract was not the same. The tablet deal I app**** for on the 4th was for a Samsung Galaxy Tab A @ R299.00/month. The contract she gave me to sign had the contract at R349.00/month. I questioned this and was told that the prices have changed since I app**** for the contract. I told her that I am not willing to pay R349.00 seeing as what I app**** for was different. She said she will contact Vodacom and sort it out for me, I just need to sign the contract. It is now 2 weeks later, and the SIM is still not activated. I have called her once asking about it, she said she has not forgotten about me and that she will keep trying. This is my second issue with a Chatz dealer, is this the norm? I will be looking elsewhere in future
