I tend to leave feedback with a thank you.Sometime a message when I can and were I feel it's deserved as well.I tend to waiver a little on feedback if things may not quite be as described but may have been easy to miss the defect and/or it could have happened during postage.If it's a unique item which I want I keep (can't be replaced)  it's just not quite the positive experience it could have been.If I receive a parcel for which I have paid $50 postage and the postage cost is $15 (in a bag) I may not leave feedback.

I will message if their is a problem.I will message before bidding to clarify anything that I have questions about.

Unfortunately not all sellers are fantastic in their customer service.Expecting an obligation that buyers serve a seller  ,other than paying and communicating problems is unrealistic  (I am thinking of this from a sellers point of view).

Save yourself the stress and don't expect it.If you get it well and good.If not don't let it upset you and don't judge buyers as rude or bad mannered on that basis...or on the basis that some don't.

Also it is worth remembering that not all people have access to or use a PC all of the time..They may only come on (access a PC) to bid and pay for something they need.If there is a problem no doubt they will let a seller know.If all is good that need to get to and use a PC isn't there.It doesn't mean that they aren't happy or thankful or anything else.The seller has the money, the buyer has their item .It's all good 🙂
