Did anyone experience buying from shopee with a status "seller own shipping"? My daughter was scammed recently. She was surprised to find out that "confirm delivered" was already the status of the shipment even no actual delivery was made. 
Is this a red flag as seller should ship only through affiliated couriers?
However, how can you be assured of the shipping mode for a non cod transaction?
Sorry if this is a late reply, I just saw this now.
Yes sir, "Own Shipping" is also an option, as I myself (as a seller) was able to do that for special reasons (my item was really large around 23kg, so I has to do a special shipping via AP Cargo, which was not one of the partner couriers of Shopee).
Having said that, even though the seller that you mentioned used "Own Shipping", you should have notified Shopee immediately regarding the "Non-delivery" or "Fraud" attempt (DO NOT press the ORDER RECEIVED button at all costs!).
Just like Paypal, Shopee holds the payment, before releasing it to the seller (once buyer acknowledges receipt of package), as a security measure. The seller now has the obligation to show proof of delivery (usually the courier receipt with tracking #) as proof.
If deemed undelivered or fraud by Shopee, Shopee will refund the payment back to you (in form of credit card reversal, Shopee wallet, etc).
DO NOT by any means pay directly to the seller (ex. bank transfer, Western Union), as that is the main reason why we shop via apps like Shopee/Lazada etc. for them to act as the "mediator".
I hope this helps, and serves a a guide/warning to other buyers
