I was a You Broadband Customer who opted for it's 12 MBPs plan.
Since joining, I faced several problems:
* Sales Rep who promised to solve my complaints, stopped picking up my phone after signup
* Took 1 week to install after payment, post regular follow up by me
* Speed was in between 1-6 mbps with high fluctuations
* Time lag of 3-5 seconds for webpages to start loading
* Downloads would restart midway.
I have cancelled my plan within 10 days.
My Advice: Buy at your own risk.
