Bad service

What to do when you on the verge of losing your employment shortly after starting to work for the company only because of breach of contract due to the ISP not keeping to their promises?! What is the use of paying for a fast speed but it's unstable, there's latency, jitter as well as the high ping.Even after many calls and complaints still nothing is done. All they say is "give us 24-48 hours" and it's now almost TWO weeks later. They also blame Octotel and escalate to them but no one has been getting back to us. Meanwhile I'm on UNPAID ISP OUTAGE till these problems are sorted. I feel as if 1 star is even too much for a review
