Useless Technical Support

Still incapable of resolving an issue in almost a week since the router was finally delivered. To date have been on the line with tech support for 6 total hours, they have tried via Facebook and still, incapable of fixing a simple issue of activating the sim card on the network. I have done the diagnostic work and have stated that the MTN Tower Rejects the Sim Card from connecting, which could either be that the sim is not activated or the APN is not resolving on the MTN side, either way, this tremendous failure on their part and still they expect me to pay for no service received?
