Please give your views as to how to resolve

Dear All

Though we match the TDS Challan and File TDS Statements in NSDL through intermediary every quarter and TDS Certificates can be downloaded from TRACES .On scrutiny I find some certiciates have fallacy in the sense some of the credits given to the payee are not captured .Please guide me as to how to resolve the same .I file TDS Return thru NSDL Intermediary who is not aware as to what to be done

Please guide me as to how to go about it so that the party be given the correct online certicficate for the TDS so Deducted 

Thanks in advance
