Poor internet

I must say I have had personal experience with vox work wise and its a great company but my LTE I have has so many problems my internet keeps on dropping.I am at a point where I don't even phone vox anymore because ether they say they are going to phone me back then they don't OR they phone me when I am at work and don't even ask them to phone later because they don't. Every month they get their money but every day its a struggle all over again.When they do attend to my call that's logged there is no problems for about a week or two but then again it starts all over again and we are back to sqaure one.I can't even watch an episode of my series at night as I timed it that a 30 minute program took me more that an hour and twenty minutes to watch when it keeps on dropping.All I ask is give me the services that we pay for because we don't get compensated for the down time.
