The account balance of -50, in their view, it should be credit balance and it is the amount owing to us.

How could they use the sign of negative -50.

Like the credit card or any billing system, when you see negative, meaning that party owing to us because such billing is prepared by them.

So negative is their account ledger negative and it is the amount payable by them...

Correct me if I was wrong.

thinking to try and clarify from YES?

Wonder if anyone has canceled this pre-registered account?

And how is the coverage if you are on the load?

The cheapest device of Yes costs how much and anyone is selling it in forums or online?

I am just doing normal office task and within 6 hours, I have used up 150MB.

If using 150x0.03 = RM4.50

RM4.50 x 20 days = RM90

That are only during office hours. What about if I go home and surf again?

I don't think YES will success in their plan.
