Account not updated on ITC

My credit card account was handed over to Norton attorneys last year. I paid it up on the 18th December 2014. I checked my credit profile today and the default is still not updated. I sent Norton attorney and email to send me a paid up letter and to update my profile and they didn't respond. I called them and they said It will take 2-3 days. They were not convincing, they didn't apologise and they were very unprofessional . They told me they closed in December that's why it wasn't done. But its the 3rd February, they had more than enough time to respond to my request. Once a client has paid they should update and don't need to remind them. Can you PLEASE remove the default as the account has been paid.
