To find a seller, just use 'advanced search', on the right of 'search' on your front page, then enter the seller's name.
I never use the bot - use 'help & contact' top left of your ebay page and enter a couple of relevant words.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
