Incompetence/ irresponsible/ bad service/ false pr

I received a new contract phone on the 11/06, 12/06 phone still not connected to network on the 13/06 called customer service and was told that it could be the Rica process, and an email will be sent to the appropriate department. 17/06 I contacted 084145, the agent who received my call said that the SIM had been Rica'd n I should make sure the old SIM is off n switch on n off the new SIM until it is working/connected. I did that the whole morning n phone still not working,called 145 again, was told to take out SIM for 20min n insert it again, still after a few hrs phone still not connected to network,I called 145 again was told they Will book the phone in. The phone was collected the same day n brought back on the 19/06 I called 145 AGAIN, a rude agent spoke to me I asked to speak to the team leader as he was too rude n wouldn't listen to my concern re-phone as it keeps saying not registered on network. I spoke to the team leader who said it could be a defective SIM card, was told to look for a nano SIM and call 140,I was told an agent will contact me in 2-4 hrs 14hrs later still nothing.I have been uncontactable since the 11th unable to receive or make calls, CELLC IS USELESS.
