Shocking service waste of time

So I have been using them for a while have a fast 60 mbps line.. I loged a fault twice last week, and no result contacting them today, they have cleared the issue how ever I still have less than 1 mbps upload and pretty slow down load. After many hours on what app I am bitterly frustrated and now need to move my whole office around again to test some thing we just did on Saturday and still have the same issue.
