This is to warn everyone to avoid Shopee if you want to avoid problems with delivery and disputes. Their customer service sucks big time and always side with sellers. I didn't know this before, until i encounter a dispute and check on Lowyat for advice - only I found out there are many similar cases in which buyers have to waste so much effort in problematic disputes!

My story timeline as follows :

12 June - Place order and paid for an Amway product
21 June - Order status still hanging at "to ship". cannot wait already since 10 days has passed and I need the item urgently so I cancel order
21 June - Seller rejected my cancellation and immediately update status to "shipped" with DHL tracking number
23 June - DHL rider called and inform me the package is empty - just a plastic package. I told them to return the package to seller.
24 June - DHL rider delivered empty plastic package and inform me to request return via Shopee as seller is refusing to accept return of the package.
24 June - I requested refund/return via Shopee
27 June - Seller raise dispute
28 June - I provided all evidence to Shopee
29 June - Seller provided statement saying item is "shipped via Amway Truck"
30 June - Shopee agreed with seller and informed that request to refund will be rejected since item is shipped
1 July - I demanded shipment details because seller has not provided any information at all
1 July - Seller provided a tracking number which can only be tracked via Amway website in which the account user (the seller himself) can view the status of delivery.

So that's what happened - 3 weeks of frustration. I had to purchase the product from another seller (it's not cheap!!) because I urgently need it - got it within 3 days too.
And for this particular seller - i still have no idea when his item is coming.
Seller has abused the delivery tracking system setup of Shopee by sending fake empty package to ensure i cannot cancel.
Shopee has supported such seller by not holding him accountable.
I have done all I can think of in this dispute, and now I am just sitting duck waiting to lose the dispute. Maybe someone have advice for any further action.

Just additional information - I did check the reviews of the seller - they are all good reviews (fake or not, i'm not sure). I've always been careful about choosing which shop to buy, and never face any problem or dispute on Shopee until now - consider it bad luck on my side.

But bottom line is - bad luck can strike anyone in terms of horrible sellers, but we get the choice to determine which platform to use - so I am definitely banning Shopee from now on!!!
