S A Yadav — mahindra and mahindra gst of rs. 145000/- not paid by sahyadri motors, on purchased bolero

We have purchased one bolero from sahyari motrs p ltd. Sus road, pune on 24 april 2018, in which they have charged gst of rs. 145, 972/- which is not filled by sahyadri motors. When we asked them, then they said bill provided by sahyadri motors to us is not system generated bill. So our complaint is for original bill is not provided to us & gst of rs. 145, 972/- not filled by sahyadri motors,
Please solve the issue on urgent basis.
