Why can’t the consultation phone number of the Trademark Office get through?

Trademark registration applications have been accepted since February 28, 2008, and have been delayed. Since the objection review was completed on May 8, 2014, After our company obtained the original reexamination ruling in mid-May, the application status has been stagnant. The telephone number of the department handling the reexamination was 010-63219181. The reply was that the status was "Waiting for registration and certificate collection time". Please call me at 010-63219616 to ask for the certificate. At that time, it was very difficult to get through to this phone number. It was either busy or no one answered. It was rare that someone answered the call. They said they didn’t have the documents to issue the certificate, and asked me to call the liberal arts phone number: 010-63219105, 63219130. To dial the liberal arts phone number, dial 2. For more than a month, there has been no answer. Please tell me when will the trademark applied for by our company be issued to us?

The ruling has been completed and the Trademark Office will issue a certificate to you, please wait patiently.
