Regarding Collection of TDS amount from Suppliers

Hi Sir / Madam,

                  I am T Kondalarao, accountant of an Enterprise. My Enterprise is under applicability of TDS U/s 194Q. We have an issue for collecting TDS amount from Suppliers, they are refused to give TDS amount. In this case, is there any solution to do......(like approaching income tax department, or any other way to do.)

                  Any one please respond to my query as soon as possible.

Thank you.
