You should keep an option for the worst product also. Instead of using ABC Broadband you can use 2G mobile internet in some China set.
I took 2 Mbps connection 4-5 months back and max time I am getting 50-70 kbps. I can share the screen shot if required. Service is the worst.
Every time latency issue, tower is down, server is slow etc etc . Engineer also visited my place 3-4 times but same story, sir fixed band width. We have escalated it, it will be resolved in 24 hrs.
Fake promise, fake people, fake service.
Friends if I am wrong choose ABC Broadband and increase your blood pressure.
