what is the last date u did successfully?

yes. i cancel my aeon bt means the one i plan to overpaid to aeon cc, so that i can cash out from my aeon cc acct. wasting time cash out from aeon if they play that "game"

it depends on if statement is needed for bank B when applying BT.
for example, PBB doesn't required statement, so you are allow to BT more than 5K.

New to PBB customer eligible for 0% interest and fee for 12 months BT. Min 3000  BT and have to spend 1000 within 3 months after approval. I've just applied.

Existing customer 2% upfront for 12months or 6 months no upfront.
Just sharing

But the BT amount is more the cc amount, cannot said double payment 

I made the request on 2/2/2016 and only saw the excess fund in my saving account this morning (I did check last Friday/Saturday online but didn't see it though) but the transaction date shown 12/2/2016. So it's within the 8 working days timeframe that MBB mentioned.

I think better try other banks for any new BT-er, and for those BT-sifu would be grateful if you could share your experiences on the efficiency of excess fund transfer for other banks
