Sim card activation problems

I have since ordered a phone online, which was also an upgrade and received the phone on the 17/04/2015.<br> <br> The phone is an Apple iphone 6 plus with a Nano sim, I have been trying to activate the sim card for the phone to but to no avail or any help. I have been waiting for more than 3 weeks to get the sim to be activated but nothing seem to be working on my side. I have a phone and sim card that is not working but my money is being debited into my account.<br> <br> I have been trying to call your activation line which is ***, to follow the instructions but nothing seems to work, the phone dose not have service and this frustrates me. I have been waiting for more than 2 to 24 hours now for the past 3 weeks.<br> <br> I am now confused and gatvol with your service sending me from pillar to post and wasting my money and time. Your service it sucks....period.<br> <br>
