I gave up.
They do not communicate with normal business.
They asked for a long paperwork.
They asked me for my job, my job, my income.
I prepared and submitted all the documents.
I declare that I am a private business.
However, they did not properly examine the documents.
They wanted a payroll certificate.
I am a private business owner, how do I get a certificate of salary income?
They do not communicate normally.
I am afraid that they will refund it properly.
