Have u explain P'Nang (Datacom) by phone call already?
For this case better call them to explain na.
As I read its mistaken from your meaning and might make them angry in can't accept their order.
Since issue is just about no overseas credit note process at SiS side, pls tell them you can correct the record to be Datacom but need them to help solving money transfer issue ja.
CC: Bee pls help Jib on this if u can krub. I want to make this issue solve by this quarter.
Note: loop Bee, K.Fon & P'Lom for info.
