I suspect the yeast has stalled because the temperature is too cold. See if you can get a heat pad from homebrew shop or online. Repitching yeast will get it going again but you need to be able to maintain a warmer temperture. Good luck.
I'd make a blow off. Plastic tubing from hardware store and 2/3 litre container with water/sanitiser. Take the bung with you so you know the right gauge of tubing to buy.
