yes, why don't u just send proof of mailing to us? u promised us will send proof, but none of us actually receive any proof from u. common sense answer again : because u didn't mail the items out that's why.
i am also a seller, i always send pics of the parcel to my buyers, this is the most basic assurance u can give to your buyers. if u mailed out the items and even tell your buyers u will send the proof, what's preventing u from sending???
especially my registered mail, u should have the receipt since singpost already issued the tracking number to you, why u cannot send to me since u said u would.
just refund all of us please. save yourself the trouble of being arrested.
