Buyer cheated Seller on ebay

[neellak123]

Hi, I sold an item on eBay, pack of 5 M&S shirts, after 1 month, may be close to 30 days, buyer raised return request saying the shirts are different size, 

I did not accept return request as the item was posted in original M&S branded packing I bought from store.

When ebay stepped in they accepted buyers return request and I was charged much higher postage cost for return plus when I recieved the item back, I received only 3 shirts out of 5.

Buyer clearly cheated me as seller. 

Ebay return request is already closed, buyer kept 2 shirts and whole set messed I can't do anything with it and was also charged higher return postage cost. I think I will avoid selling on ebay, ebay is a buyers platform where buyers are cheating sellers. 

Is there any way to send ebay formal complaint by email?

You can appeal, but doubt you will get anywhere as you chose not to deal with the case opened and ebay had to deal with it.  If you look at your seller dashboard, you will  find you have a defect.

I should add that frequently when seller does not deal with return, ebay refunds without the need for a return, assuming that as seller did not deal with the case, they do not want item returned.
