application for macau visa

Greeting
I applied for a student type for the special administrative region of Macau through the chinese consulate in Lagos.. I have paid the fees and I submitted my documents since on the 27th of september, I was told I will be called.. And I was given a pick up slip.. But it's 1st of November now and still haven't gotten any call or response from the consulate. I live in benin city. I tried writing to the Consulate on the email that was written on the contact page of their website, and also called the numbers, but no one is responding to my calls and my emails.. I have been to lagos so many times because of this. Please what do I do?
