Telkom / Celldirect - very bad service

I took up a contract from one of the call centre agents 2 weeks ago. Last week Wednesday I received my device. All calls were made and all packages confirmed including a 10 gig data for 3 months. I called every day since Monday to activate my service. I was promised every day that my service will be activated. When I called today I was told that my 10 gig was done away with and I must agree to that before they will activate my service. I have already opened that box inserted the simm card. The agent told me that they will send someone to collect the phone if I am not happy. This is extremely bad service. What am Ito do
