Q: I need to reinstate my account. I have reset my password but it dose not help.

I'm assuming that you are getting a message that the account is disabled or locked (?),  if you are then you might then need to log out and back into the account wherever you're using it : What to do after you change your Apple ID email address or password - Apple Support

If that doesn't fix it contact iTunes Support : https://www.apple.com/emea/support/itunes/contact.html

If it's a different problem ... ?
