Negative / neutral feedback for not combining postage

A buyer purchases and pays for 2 items from 2 eBay sellers.

 

Both items are sent the same day, no problem.

 

When the packages arrive they both have the same return address.

 

The buyer complains that combined postage wasn't offered.

 

It is explained to the buyer  that although the return addresses are the same the items were bought from 2 different people (seperate eBay accounts)  and was paid for through PayPal as 2 seperate transactions therefore 2 tracking numbers must be provided as you can not use the same tracking number for both purchases. It is further explained that this is because the seller would have no proof of postage if the buyer tried to claim for an item not received.

 

I believe (I am not positive) that the buyer has left negative or neutral feedback.

 

Could someone please tell me (as per the above scenario) is a buyer allowed to leave negative / neutral feedback for a seller if they don't combine postage? Also is there any way to have it removed if it has been left?

 

I am asking because I heard this happened to a friend and I am wondering if this could this happen to me? I personally have 2 different eBay selling ID's (and also this ID for occasional buying). Both selling ID's have the same return address however stock for each ID is held in a different location. When I opened the second selling ID I checked eBay policies and it said that you can have multiple accounts as long as they are in good standing.

 

Any advice is appreciated,

 

Cheers!
