Hi currently I'm using Adventure
but I got 40gb for couple of months (double even)
you see adventure is fixed cost..
From now I used more than 100gb as normal speed(ADSL2+? something like that)
what's going on here??
The telecom web says

If you use more than your monthly data allowance your connection speed will slow down to a maximum of dial-up connection speed for the rest of the month. No additional usage costs apply

I guess it's a problem with their server or etc..
If they charge me for this can I refute them with that policy??

Thanks.
