Poor Customer Service

I ordered Rain's 4Gig sim card which was delivered a few days later by RAM. It was Rica'd successfully upon delivery by the driver and an sms was sent that the simcard was active. I then tried using it but to no success because the sim card showed an 'Emergency calls only' network error message, which basically meant it won't work. I have been trying to communicate with them through their contact support option on their web page and emails but no one is helping resolve the issue. They always send emails back saying that they have received my query and that a consultant will get back to me but don't. The last response I received from one of their consultants was to follow the steps of changing my APN settings for this to work. I then responded that, changing settings cannot be done because the simcard itself does not have network therefore all those options are grey'ed out but no one has responded to that. My worry is that I am unable to work from home and I fear that I might have to pay for something that I have not even used. I asked them to cancel everything if they are unable to assist me so that I can use other reliable service providers instead, but still no response. We are all in a crisis and this company is really making things very difficult for its customers.
