Had a buyer who purchased an item BIN but didn't Pay, 1 Hour later purchased another item and pays straight away. I received a message this morning asking to cancel the first order as she has a new account with ebay and will buy the item from the new account. I canceled the sale with the option Buyer Requested To Cancel. Now under her new account she has purchased another 4 items BIN but not the original item and still has not paid for any. This Buyer on her original account had a FB of 2 now increased to 4. Advice please should I block her? Should I let it ride? After 4 Days I Will if payment is not received open a NPB, This all just seems a bit suss. The buyer is in Adelaide SA Smithfield Plains.

Why would someone open another account with same details to drop back to 0 FB from 4??

Thanks for any info
