[UPDATE MAY2015: Now I have already moved to TRUE]
I am still having problems with AIS bills. After sorted out all packages for GPRS, International SMS, Local SMS, and fixed calls, I am still very unsatisfied with AIS, specifically, the way they handle their bills.
This month, I still have seen something unwanted (double charged 400x2 for International SMS). According to the call centre, even though I cancelled it, but I had to wait until end of the month in order to fulfil my orders.
Bye for now, I am not in mood to write anything.
