Loosing my job because of no help from home-connects bad service

For the past 4 months I've had internet connection issues that has beveer been resolved and that effected my work productivity. I'm on the verge to lose my job because of that. I cancelled and want them to release my line so another service provider can connect me since lastweek but they refused. I have no positive feedback or no feedback from them. No they want me to pay till August before they release my line. I didn't pay them for this month because I've decided to cancel and have no internet to work at this moment. This is so frustrating and the fact that my daughter is a 3rd medical student and can't do he assignments that counts towards her marks for this term she can't even attend online classes which is compulsory. And all they can say is thers nothing they can do. If my daughter fail this term and I loose my job it be all because of bad service from home-connect.
