If it is a 30 day eBay Store listing that is set to auto-relist in Vendio, then you can stop it from auto-relisting.
However, if it is a Good 'Til Canceled eBay Store listing, then the only way to stop the listing is to cancel it directly through eBay.
Note that Good 'Til Canceled eBay Store listings will count down from 30 days within your Vendio account, and then start over from 30 days once they reach 0. This is not because they are actually relisting on eBay, but because you are charged a Vendio listing fee for every 30 days that the eBay Store listing is active. The count down in Vendio allows you to see when you will be charged another Vendio listing fee for the item.
I checked your account and I was unable to see any items currently set to auto-relist, so it looks like your eBay Store listings are Good 'Til Canceled, and will need to be canceled directly through eBay.
