Hello fellow card holder, I'm sorry you are experiencing such headaches.  I'm surprised they are still calling you when your account is in good standing.  Doesn't sound like them at all, but then again I'm not surprised.  Something in their system must not be up-to-date and they should be made very aware of the annoying calls and to make sure the payments are all posted to your account.  I hope by now since the date of your posting, the issue has been resolved.
