(04:46:26 AM) acbc2k: I cannot pay to Lazada despite have enough balance. Twice in a row unable to order from them. Support from Lazada told to check with BigPay.
(04:46:37 AM) Yasmin: Hi, thank you for contacting Bigpay. My name is Yasmin!
(04:46:50 AM) Yasmin: Firstly please accept our sincere apology for the inconvenience you have faced, I truly understand your frustration on this matter.
Please note that Bigpay is not a bank issued card, hence its not accepted on LAZADA platform. At the moments, Shopee accepts debit/credit card issued in Malaysia and Singapore (bank card only) for security purposes.
(04:47:08 AM) Yasmin: It was fine back then, but right now Shopee, Lazada, ZALORA has tighten their security. Thus they are declining transaction from our card.
(04:49:29 AM) Yasmin: Every other online shopping still accepting Bigpay as long as they have Mastercards terminals.
And I thought I was th e only one having issue with Lazada. Customer service just ask me to change browser clean and clear cache. Like duh I always do that. And they brush it off as if is nothing.
