Maxis Pavillion has got plenty of stock for 32Gb Black Only. Can sign up for hotlink plan too, i was there yesterday night. Suppose to sign up for 32Gb, then suddenly heard the salesperson mention Maxis Sunway has got few sets of 16Gb. So quickly rush down to Sunway, I'm lucky enough to be the last 16Gb White owner lastnight.

I think it's better to keep calling and follow up with them, waiting for them to call just doesn't work for me I guess. You only end up waiting for even longer period, sometimes they might have stock in store

FYI: Maxis Sunway has run out of stock for 8Gb, 16Gb & 32Gb lastnight. So it's better to call them and ask for stock availability before going there.
