You all get correct amount for latest bill?
My bill start on 28 of the month.
On August 28, the bill come with old amount, I email to them tell them 28-31 Aug is RM140 rate but 1 Sep to 27 Sep should be RM69 rate. They ask me wait for next month bill.

Now I received this 28 September bill. It show
Streamyx Home 4.0M RM140 26/09/2019 27/09/2019 -9.03
unifi Lite 26/09/2019 27/09/2019 4.45
unifi Lite 28/09/2019 27/10/2019 69.00
26 Sep to 27 Sep minus 9.03? suppose is 28-31 Aug which about RM18
Then 1 Sep to 27 Sep is about RM60.
Total bill for that month is RM82.68 (include sst)

But that month still RM148.40 (include sst)
Then this month should RM73.14 (include sst)
The latest bill should minus the last bill that I over pay which is 148.40-82.68=RM65.72
so it should be RM73.14-65.72=7.42
right?
