VAT TDS

Dear experts,

I am working in a private limited company , I have one doubt on Vat TDS 

We have given one contract ( 194C) to another company but the contractor  was not registered under VAT and also he is not providing invoices with VAT.

But actually contractee shold have to deduct Vat TDS while making payment but in this case contractor was not registered under VAT , So what i have to do while making payments. pls..... help me ( both contractee and contractor from Andhra Pradesh)

Thank you,
