From TmPoint they told me any bill date left during August still calculate as rm160(or what you pay per month). Only after september bill rate will calculate as rm69
Eg.
My bill is rm150 and bill is on 19/8. So i will pay from 20/8 to 31/8 using rate rm150/month(31) = rm4.84 per day and september rm69/month(30) = rm2.3
My August left 12days x rm4.84 = rm58.04
My September bill at 18/9 is 18days x rm2.3 = rm41.40
Total will be rm99.44 without tax bill at 18/9
Starting at 18/10 my bill will be rm69
So basically here this is what TmPoint told me about the calculation rate.
*Above bill rate/day may not be exact amount
Just giving the idea how tm told me.
if you look at the bill posted by @bthing above, there is no such prorated calculation.
I dont see in my bill too.
