For this kind of work, subordinate departments can do it according to the specific requirements of higher-level units, and can also implement it according to relevant rules and regulations.

Therefore, after the superior unit signs and seals the completed information, there are two specific ways to ask your department to report the matter:

1, according to relevant rules and regulations.

2. Please ask the relevant departments of the superior unit to do it according to the specific requirements of the superior unit.

Regarding the first method, it specifically includes the following three aspects:

1, prepare relevant materials according to the specific job responsibilities and work contents of the department.

2. Stamp should be stamped with the seal of the department.

3. The signature shall be signed by the department head. Or signed by the competent leader in charge of this work.

In the latter case, there are the following specific instructions and communication methods:

1, written application for instructions.

2, when facing the superior unit leaders for instructions.

3, using cross-departmental communication channels for instructions.

4, find specific responsible for the work of the superior unit related personnel to communicate.

In this work, your department has prepared relevant materials and completed the most important content of this work. All that's left is signature and seal. And how to sign and seal this matter is not big for this job, and there is no need to write a written application for instructions.

Therefore, you can verbally ask for instructions from the leaders of higher-level units, or communicate with relevant departments of higher-level units through relevant channels to solve problems.

So it is correct for you to ask the director of the superior unit and then communicate with the liaison officer of the superior unit.

As for the reason why they didn't reply, it may be because they are very busy at work and have no time to reply for the time being. You can ask for instructions and find another time to communicate.

Or, you can report this matter to the competent leader of the department, who will decide how to sign and seal it, or the competent leader of the department will work out specific measures to ask for instructions and convey this work to the superior. ..... At this time, as long as you sign and seal the prepared materials according to the requirements of the department leaders and report them to the superior unit, your work will be successfully completed.
