Supertech — supertech basera - gst demand from buyer

As per demand letter dated 2nd jun 2018 from supertech for demand of my unit (Unit no 1102 in tower 11) in their project basera in sec 79, gurgaon,
They are asking the gst amount from buyers whereas as per multiple notofications from government, gst can't be charged from buyers. If builder wants to charge gst from buyer, then builder needs to reduce the asked demand accordingly as per gst, since this is fully creditable to builder.

But despite of writing to supertech multiple times through phone, emails, registered post with all the proofs of government notifications saying "no gst can be charged from buyers", their team is continuously putting pressure to pay gst on us (Buyer). I have left with no other option except go to consumer court as am very irritated now and this is affecting me as personally also and getting disturbed.

Thanks,
