I can't understand why you're bothering your bank when it's Lazada that instigates the refund, BBL does nothing more than receive it into your account and cannot speed it up.
You'll get it when it moves through the system, same as everyone else does. If you've received a refund in the past a lot quicker than the reasonable few days that you've waited so far, you've just been unusually lucky in the past.
I make many purchases on Lazada and never pay any way other than debit card. It's done by following the payment options. Maybe the option is "pay by credit card", if that's the case (it's so many years since I set my account up, I can't remember) just enter your debit card details.
How can a debit card payment that's already been authorised and transacted be "stopped"? Once it's out of the buyers account, it's in the seller's account! I'm surprised you wouldn't realise that.
Can't imagine why anyone would ask that. Where has it been suggested that what happened "is the best that Thailand's children can expect from those who should protect them"? It was a one-off accident.
A few years? Yeah, right... many, many thousand of years, maybe. But you really think that poodles reproducing with other poodles in the wild would, eventually, turn into wolves? Brilliant, Sir David, brilliant.
