Hello LindaBelle -
For your first query, please review your Saved Listings where this has occurred - on the listing creation page there is an option to add a second category for your listings just beneath the area where you select your initial category. If you do not wish to have listings post in more than one category, the second category field will need to remain blank.
Please also note that this will not have any effect on your already active listings and if you wish to relist these listings at a point later, you will need to post from the Saved Listing after making such a change to it.
As for our Live Support - Live Support is available between 9AM and 6PM Sunday through Friday, and if our Live representatives are busy at the time you call, please leave us a message as we return calls as soon as the team is available - you can also leave a message after hours and we will return your call. If you continue to encounter difficulty with Live Support, please feel free to file a support case from under the Help tab of the site letting us know what the difficulty is so we can take a look into your accounts and assist you.
