Sim Card stil not activated

I order a Samsung S6 online on 20 July 2015, on 23 July 2015 I received an sms to say my online application has been approved within the next 3 working days the first debit order will go off my bank account. On Sunday 26 July 2015 the debit order went off and was successful. On Tuesday 04 August 2015 I received my Samsung S6. I phoned the call centre to ask how long will it take before my Sim card will be activated the lady informed me that it takes 24 hours, on 05 August Wednesday I called the Call Centre again and the lady informed me that se has send my details through so that my Sim Card will be activated once it is done they will phone me but it will take another 24 hours. Today I phoned again as my Sim card has still not been activated and once again the lady informed me that she will send my phones EMEI number through as they request that and then they will activate my Sim card but again it will take another 24 hours. How do you deliver a phone to a customer and 3 days after delivery you still can't use your phone what is the use of having a phone if you can't use it??????
