Hello, I'm Rich from China Admissions.

I did check and we did have one student from Nigeria who matches this description.

I'm sorry that the application didn't work out for you. We did give a full refund at this time. We apologies that there was a delay on that.

To give some background:
I'm afraid it can be very challenging for students from Nigeria to apply to Chinese universities.
We do have some information about it here.

Usually, we make sure that all students have a call with us first before ordering our services, so we and we will prepare the agreement for you so it is clear on expectations.

We're sorry that this didn't work for you and hope that you every success in the future.
