Product: Money transfers

Hello, My name is XXXX XXXX. I am the owner of XXXX. I recently started this company selling goods on XXXX. I use PayPal to pay for my transactions with suppliers XXXX. I do this primarily because of the protection that PayPal provides to the buyer against fraud. 
I recently had my first experience where I needed this service and it seems that this service is actually Seller protection and not Buyer protection. Here is my story : I was running very low on a product that I sell ; my normal supplier went out of business so I needed another supplier quickly. There were no suppliers of this item on the website " XXXX '' so I submitted a quote through a different website " XXXX ''. I received about XXXX or more quotes from various suppliers for the selfie stick that I currently sell. 
The selfie stick is Bluetooth and has LED lights on the clip that holds the cell phone. I eventually chose - XXXX XXXX with " XXXX XXXX XXXX, XXXX ''. 
After many email communications to the Seller ( XXXX XXXX ) we established a price along with other details. 
On XXXX/XXXX/XXXX I was provided a quote ( PI ) for the product along with photos of the product. 
XXXX pcs for {$1200.00} plus shipping {$690.00} for a total of XXXX It was exactly what I needed. That same day ( XXXX XXXX, XXXX ) I paid for the product and the shipping via PayPal. 
On XXXX/XXXX/XXXX the product arrives, but when I checked the product, I discovered that it was not the product that I ordered nor the product pictured on the Sellers Purchase Order ( PI ). It was in fact a cheaper version without LED lights. 
I contacted the supplier and told him what happened. He ( XXXX XXXX ) apologized a lot for the mistake. 
His resolution was for me to purchase the correct clip with the LED lights from them and they would pay to ship them to me. Then I could open each of the XXXX boxes and replace the incorrect part with the correct part. So his fix was I buy XXXX correct clips at XXXX each ( {$1200.00} ) then I spend hours opening all of these and exchanging parts. 
The solution I offered him was for me to return the product at his expense. He gets the shipping a lot cheaper than I do. And I paid for the shipping to me. 
My XXXX product has now been out of stock and it has cost me about {$10000.00}. I do n't think I should have to pay again due to this seller 's deception. ( I honestly do n't think it was a mistake. ) I disputed this with PayPal on XXXX/XXXX/XXXX. I then escalated it to a claim on XXXX/XXXX/XXXX because the seller does not want to do the right thing and pay to have his product returned to him. 
On XXXX/XXXX/XXXX I received PayPal 's resolution to the claim. The resolution was for me to return the product to the Seller at my expense and they would refund the {$1900.00} to me once the seller has his product returned in the same condition it was sent. 
For me this is absolutely ridiculous. It will cost me more than I paid for the product just to return it. I do n't get the discounts that they have. 
So not only have I lost the current {$10000.00} in sales due to being out of stock. The sales momentum is now lost so the product is pretty much dead unless I re-due all of my marketing and promoting the product. I also lost the {$1900.00} that I spent to restock my product. 
This seller is loosing absolutely nothing. Even if the seller pays to have the product returned, they are only out the shipping cost. While I have lost HUGE, I could not even get a response from PayPal. 
They never asked to see the PI the Seller sent me ... nothing. 
I have proof of my loses. I have the ( SCAM ) PI provided by this seller. I have emails where the seller admits they made a mistake. The only thing I do n't have is BUYER protection.
