Good for you.
Just to be clear, somebody (I don't know if it was you or not, can't be bothered to check) suggested that you are safe making purchases from official stores in Lazada.
I provided anecdotal evidence refuting this claim based on my own personal experience.
That you had a different experience doesn't alter the experience I had, and therefore doesn't dispel the conclusion that it is, in fact, not always safe when you are using official storefronts.
I'm not saying that customer service is generally bad (I've mostly had good experiences). I'm just saying that I did have an incident that after months has not been resolved, and that incident did happen with a purchase made though an official store.
Incidentally what steps did you take to initiate the refund request? The only method I can find is via the chat. If there's a button somewhere that I can click which will start the process without having to deal with support staff, maybe I'd have better luck.
