Look, phone company ish liddat one.. if u dun spend above a
certain amount a mth, they wun auto give u voucher.. most
singaporean just guai guai pay, at most call in and grumble.. but
we never assert ourselves.
Tell u wad, if ur contract is at least past 1 year, give M1 a call
n say "hi, I'm a loyal customer who's thinking of getting a new
phone and extending my contract, so I'd like to request for a
recontract voucher."
They won't refuse u.. but if u dun hear from them within 2 weeks,
call in again 
Sure will get
something one. Or at least they will tell u exactly when u can call
in again to ask for the voucher.
