****ed

I have purchased sim card from rain of R478 with unlimited data 4g, money was taken upon my purchase on Monday and I received my simcard yesterday however the him card is not working I have complained with rain via email as no one answers they calls but still no responds and I have tried to chat with them but still no help. My money is now with rain and they do not care about the service they must provide. I took up this sim to work at home but now I can't even work.
