Charged 3 times

[ricash-4476]

How do I find the user name of the seller that I used to buy something?

At the top of a normal ebay page look under my ebay for

Purchase history.

If you see three identical charges on your statement or bill, examine them closely to make sure that one is not actually a credit; if you are double-billed by mistake, it is not uncommon for that to be caught quickly by software, and often a credit is quickly issued for the second charge.

What does being charged 3 times and finding an old seller have to do with each other? You need to ask them as two questions. The first in the title, more information, maybe on what you are seeing or?
