Been following this company's issue since that thread that got taken down. I was one of the lucky customers who got my refund back thanks to that thread, and I can tell you that actual numbers like deadlines is something they will not likely give out - I'm quite sure the other customers all went through the same hell of getting a "next week/month" reply each week/month they asked, followed by a note saying how it is someone else's fault (i.e. suppliers, who can't even answer you).
It goes to show how professional this team is - customers pay you to solve their problem, not listen to yours. If you screw up dateline, MAKE UP for it instead of buat bodoh.

Hi TS,

Since you mentioned that you are based in Penang, you might want to look into Asus ROG STRIX series for something with similar specs and budget next time. The experience from purchase to service had been very good for me:
1. Hari ini order, besok sampai. Payment is only released after confirming that you received the laptop (Shopee). You won't be grabbed by the balls for weeks/months.
2. Proper hardware (i.e. Intel SSD vs mystery brands) and warranty (Service Centre is in Penang island itself, you can choose to walk-in or arrange for pick-up)
3. Sent in for repairs recently. They gave clear instructions on how to debug/prepare/package before handing it over to their SC in Bayan Lepas. No questions asked for complete MoBo replacement other than getting my approval to reformat SSD for final validation to ensure that everything works fine before shipping back to me. Anything that requires timeline (i.e. ETA for parts to arrive or repair completion/updates) they gave actual dates so that you can track.

And yes, do escalate to KPDNHEP ASAP as suggested. With all the slow-mo ping pong going on between you and them, it's a sooner or later thing before your warranty expires, then it's all on you already XD
