You can contact the registrar that you got the name thru. And, request
that they delete xxxxxxxTMxxx.com
Most of the time they will request of you to fax a letter confirming
what you want to be deleted.
They will remove it from your acct. and set it for deletion, as if, you
had not paid the renewal fee. It will go thru the 45 day period, etc.
It doesn't cost you to delete it. But, they will not give you a refund.
And, then, someone else will re-register it, thinking that "TM Corp"
forgot to renew it.
I think Bidawinner has the best suggestion. And, if you don't want
to contact the company. No problem. When it comes up for renewal
and they ignore it. Shame on them!
