I have been using Lazada.com.ph for around 3 years now. I have not had any major issues with them. I have received some defective items before, but the refund/replacement process was pretty simple (just return the item including the package and the return form and leave it at an LBC shop), once they have confirmed that LBC has the item, they will immediately send a replacement or issue a refund.
Tip:
- ONLY purchase items from LEGITIMATE or TRUSTWORTHY sellers (sellers with above 80% rating). For example, Lazada, LuckyHR and etc...
