Back on Monday I placed an order with Shopee for some expensive shaving cream which was being sold a few hundred baht cheaper than on other sites. It arrived a short while ago and we paid cash on delivery, on opening it was completely the wrong item being some very cheap body lotion. My wife immediately telephoned the courier driver who told us to go to their office. This we did and a helpful girl checked the supplier online and confirmed that they were a crooked outfit who they have had many problems with. As money was still in possession of driver and not been banked we got an immediate refund from Kerry and left the office wiser.
I’m well aware of if something is a bit too cheap then buyer beware but we all can fall into the temptation once in a while, memo to myself is listen to myself in future. 

Great information!  I have never heard of anybody getting an on the spot refund of a paid COD from a carrier as the OP did, especially from an online seller.  In my own experience, COD refunds have been difficult to receive.  

Next time I will know to notify the carrier immediately if discovering a fraudulent product.

Excellent resolution! You would expect Kerry to say that they only deliver the parcels, in this case you accepted and paid for it and must sort it out with Shopee.

Good job ! Pleased you were able to resolve it that way.

But I would suggest this is an exception and not the general rule and buyers unfortunately fall into this familiar con and not all couriers will handle it as well as your particular office did.

Good result.
