+1 for sharing link. Did you get refund?
TS can claim for refund since Lapsapda already accepted TS' return.
You let seller take your money and product purchase? Isn't that theft!
Yes, lazada and shopee are legal scam, making difficult to impossible claim on bad purchase, warranty, scam, guarantee then drag out the case to court citing T&C. KPDNHEP also play dumb no respect for MY laws.
