can a gamertag or PSN account be successfully deleted?

I want mines to go away, so it wont exist online anymore and other can claim the name. I was wondering do I have to call or this can never be done.

Change the account passwords to something elaborate that even you won't be able to remember for long. Delete all information from the HDD's of each console. Done.RandolphScott

but will this free up the names again?
