You can return them straight away. They gave you a form to print right? Those are the shipping papers.

I think they will judge if the return is valid by looking at the item when it reach them. Itshould be ok if you follow the required item state to be returned. Like all accessories need to be there, labels still intact, etc.

I chosen return to credit card previously. Took a few days I think.

Yeah return if its broken. Nowadays, I look at my local phone shop for tempered glass before checking Lazada. Most of the times they sell it quite cheap like RM 10-12 then I'll just buy it, quality is more or less same.

Lazada maybe can get cheaper after coupon and cashback but the difference is not that big.

Good choice. I think they return by the CC you used to pay.
