Erm, what has this to do with suspension of Maxis broadband account for going over the usage allocated per month?

Can you produce some concrete proof to back your statement? I am interested to know about this.
Well if you can't and post solely on hunch, then it's better not to post about it next time.

What is the average data transfer/bandwidth that you used per month? Mind to elaborate?

If that's the case then you probably aren't the top 50 bandwidth hoggers in Malaysia. Why didn't you ask the Supervisor to show you some statistics?

At this point of time I would recommend you to stop subscription with Maxis broadband and try out other broadband choices. Yes, there is 3GB limit imposed by Maxis, but as far as I know, some manage to download more than that while some get limited after they hit the limit. Therefore, it is pretty much subjective..
