I apply MyDeposit scheme last year but my loan application got rejected due to my PTPTN outstanding. Surprisingly, my application for MyDeposit had approved last week. Can I proceed to buy house within this 1 month? Or can I postpone this scheme?

because my seller is unwilling to sign the letter said that this money is belong to me as per my lawyer request. my S&P sign at June2016 I apply mydeposit at May2016 and mydeposit approve at feb2017.so now seller said that our transaction is already close, so why still want sign for it, I try to explain to but he is unwilling to help me sign. so im unable to provide lampiran G yet. closing date is at 10/3. so sad! my $$$ fly away.

THANK you for reply and help.
lawyer insist want seller to sign that letter said that this money is belong to buyer which is me instead of given to seller as deposit since our case is close.
Seller insist don want to sign for it.
just can said im bad luck enough.
