How do I cancel the automatic Relisting of an item please ?

I have gone to the listing to edit but I can't see anywhere that talks about automatic relisting.    I have 70+ finishing today and no idea how many times they have relisted.   Don't want to get stung with huge fees.    If they have relisted 3 times and then finish will they just sit in Unsold (item not relisted)? and then I have the choice of relisting if I want to?     Thanks in anticipation of your help.
