Worst service ever

They will tell you there is 24/7 support but that's all a lie. I mean I placed an order for a sim card on Tuesday afternoon. I got an sms on Wednesday to say my sim card will be delivered in the next three business hours. I canceled all plans so I can be home to receive the sim card. They didn't deliver the sim card and when I tried to find out the whereabouts of it, I got a response from Gregory P telling me that the courier guys are swamped but he will follow up with them. I must expect the delivery between now and the end of working day. He never bothered to get back to me with the feedback from the couriers. The courier guy called me on Thursday morning to deliver the sim card. I had the sim card but there was no APN settings. I sent the very same Gregory P an email but as usual he never responded. The ****** sim card has never worked and I tried getting help from the support team but they all cannot help me. What am I supposed to do now. I mean I've had the sim card since Thursday morning, today its Sunday and I still haven't been assisted yet they claim there is 24/7 support??? This is such an inconvenience as I now have to keep buying data on my phone to Hotspot and work.
