i have found the setting!!
Thank you so much for your guidance because it has prompted me to look around and check all of the settings.
I had set up a new Vendor in the Shoppers section and added the email address.
What I needed to do was to go into the original Vendor details and replace the email in there to the one that is linked with Joomla.
I have set the business email up to forward to the store owner and myself so things are running nice and tidily now.
Not sure if this is the 100% correct method but it works a treat
Thank you once again for taking the time to help with this
