We regret as a co seller for your difficulty to sell and the action taken by T & S.
1. You should have received mail from eBay team about the restriction atleast after they restricted and with the reason.
2. You will be able to see the reasons at My eBay -> Selling; then in this page; Account-> Seller Dashboard; there click; Policy Compliance.
or use this direct link:
http://cgi6.ebay.in/ws/eBayISAPI.dll?SDPolicy
In above 2 ways, you can have a clue on why the restriction was made. Hope you can post it here, if it is ok.
And with the mail you received, you need to send or reply them back with CC inrswebhelp and to your account manager seeking help.
The CP (Copy Paste) is nothing new for them especially for Sellers. Generally, this happens with few eBay executives as they would not read the problem but just read the title and then CP; again they do their own personal work.
But there are exciting responsible folks on eBay TS.
