Target Target Store, Target Corporation They canceled 2 "gift card with purchase" items & hours of calls they still can't get the cards on my account.

They canceled 2 "gift card with purchase" items & hours of calls they still can't get the cards on my account.  I have repeatedly called them to fix the issue and they still have yet to put the money on my account. They are telling me that they are getting bounce backs on my email but they keep telling me that they cannot change my email address. 

Their latest "solution" is that they can put the money they owe me on my account, and both times, having waited for a combination of calls spending hours on the phone, the money has still not happened. 

Don't buy their gift card with purchase items, they seem to selectively choose who they don't want to have them, that is all I can assume since this seems to be happening to me.
