what is going on

So I have done my trade test in April 20th and now 6 weeks later I went back to fetch my results with my trade certificate only to find out they want my school certificate to apply for my red seal. What does my school certificate have to do with my trade certificate? Then they told me after applying for my trade cert it would take 3 to 6 months? This is BS!!! I want answers from Ndlela ASAP
