Multiple buyers not paying for auctions

[thrifty.mcnifty]

Hey,

I've been running a few auctions every week and I have 4 buyers who have not paid. 1 is over 3 weeks, 1 person won 4 auctions, and 2 more people.

With the new simple delivery you cant send a payment reminder via ebay - you can only send a message. So basically ebay is not aware. 
I have sent them all multiple messages with no reply. Obviously very frustrating but the only option is for me to cancel?
I have asked all of them to cancel and just been ignored, they all have 100% feedback with recent orders aswell.

Point is I don't want to cancel and have ebay hold multiple cancelations on me. 
Is there a way to ask ebay to step in?

Thanks so much!

You can cancel using the "non payment" reason after 4 days.   Absolutely no damage to your account but the buyers get a defect and risk suspension.   More info:

Put their ID on your blocked bidder list:

And use this link to put a general block on buyers with a history of non-payment, etc.:

tick "Update block settings for active listings" and then save changes at the bottom.
